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: (Cone Bore)
Standard Grade P2 = 0.0015mm –> 1.5 microns
Special grades developed for high precision grinding machines
‘Q’ Grade = 0.0010mm –> 1.0 micron
‘QK’ Grade = 0.0005mm –> 0.5microns
Axial Run-out: (Cone Face)
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)
