Plain Cup – The basic single row bearing can be used in light to medium loaded applications, and provides a simple, cost-effective arrangement.

C Type – The flanged cup version enables through boring of the housing for simplicity and accuracy.

G Type – Double row bearings offer nearly twice the capacity of the equivalent single row bearing, and are therefore used in more heavily loaded applications.

H Type – Double row bearings offer nearly twice the capacity of the equivalent single row bearing, and are therefore used in more heavily loaded applications.

P Type – This single row bearing has an extended outer ring, housing a number of springs. It is mounted in conjunction with either a single or double row bearing. As the outer race is free to slide in the housing, the spring force ensures that a constant bearing system preload is maintained despite thermal expansion due to varying temperature conditions.

Bearing Assembly Tolerances

Radial Bore Run-out:

  Standard Grade P2 =  0.0015mm – 1.5 microns

  ‘Q’ Grade  =  0.0010mm – 1.0 micron

  ‘QK’ Grade  =  0.0005mm – 0.5microns

Axial Run-out:

  All Grades  =  0.003mm – 3 microns

Unit of Measurement

  • Metric sub division.
  • Micron - from Greek word – ‘ Mikron ‘.
  • 1 million microns = 1 metre.
  • 1 thousand microns = 1 mm.

50 microns = width of single human hair. (approx example)
