Hi-Temp ball bearings are designed to run at elevated temperatures at various operating ranges.
Deep groove ball bearings are available in radial and axial designs for many different variants. Single-row deep groove ball bearings are available in open and sealed designs. They are designed for high to very high speeds and can accommodate radial as well as axial forces. Double-row deep groove ball bearings correspond with single-row deep groove ball bearings in design and are used when the radial load capacity of single-row deep groove ball bearings is insufficient. Axial deep groove ball bearings are available in single or double-direction design variants. These bearings are especially well suited to high axial loads.
Single-row angular contact ball bearings are self-retaining units with solid inner and outer rings and ball and cage assemblies with polyamide, sheet metal or brass cages. The raceways of the inner and outer rings are offset from each other along the bearing axis. The bearings are available in open and sealed designs. Their angular adjustment facility is very limited. Double-row angular contact ball bearings can support axial loads in both directions and high radial loads. They are particularly suitable for bearing arrangements in which rigid axial guidance is required.
Self-aligning bearings are bearings with 2 tracks on the inner ring and jointly convex tracks on the outer ring. Due to this construction, self-aligning bearings have angular freedom. Light tilting of the shaft from the housing is possible. Therefore, they are best suitable for cases in which misalignments and shaft deflections could occur. Self-aligning bearings are produced with cylindrical and conical boreholes. In case of conical boreholes, a clamping sleeve is usually necessary for the assembly.
Single-row cylindrical roller bearings with cage are units comprising solid inner and outer rings and cylindrical roller and cage assemblies. The outer rings have rigid ribs on both sides or no ribs, and the inner rings have one or two rigid ribs or are designed without ribs. The cage prevents the cylindrical rollers from coming into contact with each other during rolling. Cylindrical roller bearings can be supplied with or without a cage
Tapered roller bearings can support high radial and axial loads. They have a broad range of speeds. They are efficient at supporting forces and ensure a precise and rigid shaft guidance system due to the large effective distance between the bearings. Tapered roller bearings can be adjusted and dismantled, which makes mounting easy.
Delivering an outstanding performance: Spherical roller bearings are designed for systems in which high loads must be supported and shaft flexing and misalignments compensated. They deliver extremely high performance and are designed to carry extreme loads. The decades of experience our engineers have gathered combined with innovative ideas improve our spherical roller bearings even further.
Thrust ball bearings are classified into those with flat seats or aligning seats depending on the shape of the outer ring seat (housing washer). They can sustain axial loads but no radial loads. For Single-Direction Thrust Ball Bearings, pressed steel cages and machined brass cages are usually used The cages in Double- Direction Thrust Ball Bearings are the same as those in Single-Direction Thrust Ball Bearings of the same diameter series.
Spherical roller thrust bearings are similar in purpose to ball thrust bearings in that they are designed to handle loads primarily in one direction. But unlike their ball-based cousins, the cylindrical design of the roller thrust bearing means they can handle heavy radial and axial loads, while operating at moderately high speeds. These bearings are also self-aligning and can accommodate shaft misalignment relative to the housing. Unlike some other bearings, the internal design of the spherical roller thrust bearings are not standardized by the ISO, so there is variation between manufacturers. The bearings are usually manufactured from either steel, brass or sheet steel. They are often found in applications such as marine propulsion, gearboxes and extruders for injection molding.
Needle roller bearing is a special type of roller bearing which uses long, thin cylindrical rollers resembling needles. Ordinary roller bearings' rollers are only slightly longer than their diameter but needle bearings typically have rollers that are at least four times longer than their diameter. Like all bearings, they are used to reduce the friction of a rotating surface. Compared to ball bearings and ordinary roller bearings, needle bearings have a greater surface area in contact with the races, so they can support a greater load. They are also thinner, so they require less clearance between the axle and the surrounding structure. Needle bearings are heavily used in automobile components such as rocker arm pivots, pumps, compressors, and transmissions.
Slewing bearings comprise an inner ring and an outer ring, one of which usually incorporates a gear. Together with attachment holes in both rings, they enable an optimized power transmission with a simple and quick connection between adjacent machine components. The bearing raceways, in conjunction with the rolling elements and cages or spacers, are designed to accommodate loads acting singly or in combination and in any direction.
For applications where the bearings cannot be directly fitted inside the machine or equipment, separate bearing housings are needed.
Plummer blocks are the most commonly used types of bearing housings – designed for predominantly vertical loads directed towards the base. Usually made of cast iron, these are designed for use with self-aligning ball bearings and spherical roller bearings – either mounted or adapter sleeves or having cylindrical bores.
A proper lubricant will reduce friction between the internal sliding surfaces of the bearings components and reduce or prevent metal-to-metal contact of the rolling elements with their raceways. ... Lubrication, especially circulating oil will also remove heat from the bearing. When a bearing must perform under demanding conditions, the lubricant selection becomes critical. Lubrication will affect life, torque, speed, noise, grease migration out gassing, temperature and rust prevention of the bearing.
Ballscrews consist of a screw spindle and a nut integrated with rolling elements that cycle through a return mechanism. Ballscrews convert rotary motion into linear motion, and are most commonly used in industrial machinery and precision machines. We provide a wide range of ball screw configurations to satisfy your special application requirements. Hiwin has the capability of producing JIS C0 class ground ball screws, and DIN 5 class (up to 23 microns) for precision rolled ball screws. Ball screw O.D. ranging from 4mm to 120mm, and with Dm-N values up to 220,000.
Linear guideways provides linear motion by re-circulating rolling elements between a profiled rail and a bearing block. The coefficient of friction on a linear guideway is only 1/50 compared to a traditional slide and they are able to take loads in all directions. With these features, a linear guideway can achieve high precision and greatly enhanced moving accuracy. We offer multiple linear guideway series, each featuring different options for sizes, loading capabilities, accuracies, and more.
Crossed Roller Bearings consist of an outer ring, an inner ring, and a plurality of rollers and spacers. The roller lies between the inner and outer ring with the spacers placed between the rollers to prevent the mutual friction between them thereby decreasing the torque resistance for rotation. There are six types of Hiwin Crossed Roller Bearings comprising of, the split outer ring type (CRBA), the split inner ring type (CRBB), the high rigidity type (CRBC), the split outer ring with mounting holes (CRBD), the high rigidity with mounting holes (CRBE) and the customized type (CRBX).
