End Caps

TR housings from size 204 to 208 are available machined to take the TR END CAPS with either inch or metric inserts. The end caps are NOT suitable for the standard TR housings and cannot be retrofitted.

We also have stock of a number of RHP Self lube bearings with plastic end caps.


General Operation Limitations

Flange units are suited to applications in which static misalignment of up to 2deg must be overcome, but are not well suited to high speed, dynamic misalignment applications where an internally aligning bearing sytem should be used.

Operating temperature range -20 to +100 Celsius. At temperatures above 70 Celsius grease degradation should be considered as the limiting factor. High temperature units are available.

The limiting speed is dependent upon the quality of shaft used (See Technical section).

Bearings with eccentric locking collars

The UCFL 200 series is available with inserts featuring eccentric locking collars - TR designation SAFL2G series or RHP SFT -EC series

Bearings with tapered bore and adapter sleeves

Both the UCFL 200 and UCFL 200 Series are available with inserts featuring a tapered bore and supplied with and adapter sleeve for positive shaft locking on inch and metric sizes up to 60mm.
