TR housings from size 204 to 208 are available machined to take TR END CAPS.
The inserts can be either inch or metric sizes. The end caps are NOT suitable for the standard TR housings and cannot be retrofitted.
General operation limitations
Pillow block 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 to order.
The limiting speed is dependent upon the quality of shaft used (See the Insert Technical section).
Bearings with eccentic locking collars
The UCP 200 series is available with inserts featuring eccentric locking collars - TR designation SAP2G series, or RHP NP-EC Series
Bearings with tapered bore and adapter sleeves
Both the UCP 200 and 300 series are available with inserts featuring tapered bore and supplied with an adapter sleeve for positive shaft locking on inch and imperial shaft sizes up to 60mm
