Angular Contact Ball Bearings

/0 Comments/in , , /by

 

Supertembo offers one of the most comprehensive ranges of Angular Contact Ball Bearings designed to meet OE manufacturers’ demanding requirements.

These bearings have a contact angle that enables them to withstand significant axial loads in one direction together with radial loads. They are generally used in pairs, triplex sets, quadruplex sets, or multiplex sets since an axial component is generated when a radial load is applied.

 

 

 

 

Product Features and Benefits:

  • High-Quality Steel – Bearing life extended by up to 80% with Ultra clean steel.
  • Advanced Grease Technology – Special lubricants can extend grease life and increase performance.
  • High-Grade Balls – Smooth and quiet operation even at high speeds.
  • Super Finished Raceways – Specially refined to reduce noise and improve lubricant distribution.
  • Contact Angle – Available in 15, 25, 30 and 40-degree angles.
  • Patented Seals – Prevent contamination in the toughest environments.
  • Cages – Available in a range of polyamide, steel and brass cage assemblies.

Supertembo’s range of  Angular Contact Ball Bearings includes double row angular contact ball bearings, four-point contact ball bearings, single row angular contact ball bearings, sealed angular contact ball bearings, duplex angular contact ball bearings.

Self-Aligning Ball Bearings

/0 Comments/in , , /by

 

Self-Aligning Ball Bearings

are ideal when the alignment of the shaft and housing is problematic and the shaft may bend. The outer ring has a spherical raceway with its centre of curvature coinciding with the bearing.

This allows the axis of the inner ring, balls and cage to deflect to some extent around the centre of the bearing. The axial load capacity is low since the contact angle is small. Under normal loads, the permissible dynamic misalignment is approximately 0.07 to 0.12 radian (4 to 7 degrees).

 

 

Product Features and Benefits:

  • High-quality steel – Ultra clean steel helps extend bearing life extended up to 80%
  • Pressed steel and polyamide cages available
  • Advanced Grease Technology – Lubricants that can extend grease life and performance
  • High-grade balls – Smooth and quiet operation even at high speeds
  • Super Finished Raceways – Refined to minimize noise and improve lubricant life and distribution
  • Sealed versions are available

Self-Aligning Ball Bearings

Thrust Ball Bearings are composed of a “washer-like” bearing ring with raceway grooves for the balls and are classified into flat seats or aligning seats. Designed to handle thrust loads while operating at high speeds, these ball bearings are able to sustain axial loads but no radial loads.

 

Available in two designs:  single direction and double direction. Single direction design includes two rings, referred to as shaft and housing washers and a single ball and cage assembly. Double direction design, on the other hand, includes three washers and two ball and cage assemblies. The ball and cage assemblies of the double direction type are separated by the shaft washer.

 

 

Product Features and Benefits:

  • Two designs available:  single direction and double direction.
  • To accommodate initial misalignments in an assembly both design are available with spherical aligning seats or aligning seat washers.
  • High-quality steel – Ultra clean steel extends bearing life by up to 80%.
  • Advanced grease technology – Special lubricants that can extend grease life and performance.
  • High-grade balls – Smooth and quiet operation even at high speeds
  • Optional seating rings take initial misalignment.

Supertembo’s range of Thrust Ball Bearings includes angular contact thrust ball bearing, single direction thrust ball bearings, double direction thrust ball bearings.
