Angular contact bearings

Angular contact bearings’s designed

Angular contact bearings are designed such that a contact angle between the races and the balls is formed when the bearing is in use. The major design characteristic of this type of bearing is that one or both of the ring races have one shoulder relieved, or higher than the other. In order for these bearings to function properly, they must be assembled with a thrust load. This loading (or preload) creates a line of contact (or contact angle) between the inner race, the ball, and the outer race. The preload can be built into the bearing or created when the bearing is Inserted into an assembly. The contact angle varies from 15° to 40° and is measured relative [...]

High Speed Angular Contact Ball Bearings

Super Precision High Speed Angular Contact Ball Bearings are designed for rigid, high speed, high tolerance applications. Spindle bearings used in pairs in a ‘back to back’ or ‘face to face’ arrangemet can support axial forces on both directions and moments. Bearings in a tandem arrangement can only support axial loads in one direction. Spindle bearings are available with a 15 degree or 25, 30 degreee contact angle. Various cage options are available as well as the use of ceramic balls which allow for higher speed.

Angular Contact Ball Bearings

Due to their internal design, angular contact ball bearings can withstand high radial-axial loads and reach high speeds. They are asymmetrical for manufacturing reasons and can withstand unidirectional axial loads only. Angular bearings are usually mounted in a group of two or more opposed preloaded units with rigid or elastic spacers. Typically, the inner and outer raceways and balls are made of chrome steel. Where operating conditions are severe, bearings may have ceramic balls creating a hybrid bearing.

Angular contact ball bearings

Angular contact ball bearings have inner and outer ring raceways that are displaced relative to each other in the direction of the bearing axis. This means that these bearings are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads. The axial load carrying capacity of angular contact ball bearings increases as the contact angle increases. The contact angle is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the combined load is transmitted from one raceway to another, and a line perpendicular to the bearing axis.

Thin-section sealed four-point contact ball bearing

Thin-section sealed four-point contact ball bearing is also designed for mounting sealing device on both sides on the basis of thin-section four-point contact ball bearing. We have many options for the structural form of the sealing device. The speed is lower than thin-section four-point contact ball bearing.

Tapered Roller Bearings

Tapered bearings are uniquely designed to manage both thrust and radial loads on rotating shafts and in housings. We manufacture nearly 26,000 bearing combinations – in single, double and four-row configurations. Customized geometries and engineered surfaces can be applied to these bearings to further enhance performance in demanding applications.

Timken Tapered Roller Bearing

Tapered roller bearings consist of four interdependent components: the cone (inner ring), the cup (outer ring), the tapered rollers (rolling elements) and the cage (roller retainer). Tapered roller bearings are uniquely designed to manage both thrust and radial loads between a rotating and non-rotating member. The steeper the cup angle, the greater the ability of the bearing to handle thrust loads. Industries: Aerospace, agriculture, automotive, heavy truck, cement, aggregate, coal, oil and gas, construction, gear drives, machine tools, mining, paper, metals, rail and wind. Benefits: Enhanced performance in demanding applications.

High Speed Angular Contact Ball Bearing

Angular Contact Ball Bearings are designed with offset raceways between the inner and outer rings which creates a specific contact angle under load. Due to this configuration, these bearings are well suited to carry combined axial and radial loading. Single row bearings can carry axial loading in only one direction and are almost always sold in pairs or adjusted against another bearing. Angular Contact Ball Bearings have one shoulder removed to allow for a greater compliment of balls than standard Deep Groove Ball Bearings. These bearings are good choices for high speed applications and can be produced to an ABEC 5 precision class.

Angular Contact Ball Bearings

NSK’s ROBUST Series of Ultra High-Speed Angular Contact Ball Bearings for machine tool main spindles offer improved thermal robustness, low heat generation, improved seizure rates and low noise. This ensures that machine tools can operate at ultra-high speeds, increasing manufacturers productivity while reducing energy costs.

Ultra-high speed angular contact ball bearing

The new bearing meets the increasing demand for higher accuracy, higher speed rotation and design for the environment of bearings for the main spindle of machine tools, thereby helping to improve their productivity and environmental friendliness. In terms of running accuracy, the demand to reduce RRO (repeatable runout) and NRRO*(non-repeatable runout) in particular is growing stronger. At the same time, there is strong demand for higher speeds and lower heat generation. Reducing NRRO of the main spindle of machine tools improves the process surface quality, and reduced heat generation helps suppress thermal displacement, thereby improving processing accuracy. In particular, this new product is very beneficial to the surface quality of dies and gears processed by machine tools. In addition, these higher [...]
