Angular Contact Ball Bearing

Widi is angular contact bearings manufacturer and supplier. Our 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.

An angular contact bearing (spindle bearing) is expertly crafted for speed and precision and is a great choice for applications that:

  • Operate at high-speeds,
  • Need bearing load support,
  • Need rigidity.

Angular contact ball bearings are designed for combination radial and axial loading. Single-row bearings have high thrust capacity in one direction. Some single-row bearings are specifically designed for duplex mounting in sets for maximum performance. Double-row Conrad bearings can accommodate thrust in both directions.

Types of Angular Contact Bearing

There are many types of angular contact ball bearings. We supply these types of bearings:

  • Single row angular contact ball bearings
  • Double row angular contact ball bearings
  • Four-point contact ball bearings
  • Super-precision angular contact ball bearings
  • Fixed section angular contact ball bearings

Angular Contact Bearing Options

If you have specific customization needs, check with our bearing technicians to get the right bearing designed, manufactured and ordered.

  • Cage Material: Phenolic Resin (standard) or PEEK with Carbon Fiber.
  • Ball Material: 52100 Bearing Steel, Ceramic (Silicon Nitride, Si3N4).
  • Contact Angle: Offered in 15, 25, 30 and 40 degree angles.
  • Preload: Light, Medium, Heavy or Spring-Loaded.
  • Sealed Bearings: Bearing Sealing Types.
  • Lubrication: Grease or Oil.
  • Direct Oil Lubrication: On request we can provide a small hole on the outer ring of the bearing for lateral oil supply.
  • Grease Lubrication: Similar to the direct oil lubrication, except a slightly larger hole on the outer ring for the grease supply.
  • Tolerance Options: PN (standard), P6 (Abec 3), P5 (Abec 5) , P4 (Abec 7) or P2 (Abec 9).

Applications of Angular Contact Bearings

Four-point Angular Contact Ball Bearings

Four-point Angular Contact Ball Bearings

Four-point angular contact ball bearings are radial single row ball bearings with raceways that are designed to support axial loads in both directions.
Double Row Angular Contact Ball Bearings

Double Row Angular Contact Ball Bearings

The design of double row angular contact ball bearings corresponds to two single row angular contact ball bearings arranged back-to-back.
Single Row Angular Contact Ball Bearings

Single Row Angular Contact Ball Bearings

Single row angular contact ball bearings can accommodate axial loads in one direction only. It is typically adjusted against a second bearing.
