The PEER GRHA hanger bearing unit is a mounted bearing with a pendular housing that is fastened to a structure by means of a top flange. It is used to support rotating shafts in conveyors, elevators and transmission lines, where alignment may vary. Its design allows mounting in any orientation and makes greasing and replacement of the insert easier.
The GRHA designation identifies the PEER hanger bearing unit series. The number that follows indicates the nominal shaft diameter and, when a hyphenated suffix appears, the inch measurement or the fastening variant. For example, GRHA204-12 and GRHA204-13 correspond to 3/4" and 13/16" shafts respectively, while GRHA205-13 to GRHA205-16 cover measurements from 13/16" to 1". To choose the correct code, have the shaft diameter and the mounting type on hand.
These units are used in belt and chain conveyors, bucket elevators, mixers, screens and process equipment in food, chemical and aggregate plants. In the USA, Canada, Mexico and South America, they are common in the oilseed and milling industries and in waste treatment plants. Their oscillating capability compensates for slight misalignments and absorbs vibrations, which extends the service life of the insert bearing and reduces maintenance downtime.
To select the unit, check the shaft diameter, the expected radial and axial load, and the environmental conditions. In dusty or humid environments, choose inserts with reinforced sealing and keep up periodic greasing. During mounting, make sure the flange is firm and that the shaft does not transmit additional stresses. Lubrication should be renewed according to the duty cycle, and it is advisable to check clearance and alignment after the first hours of operation.
PEER GRHA hanger bearing units can be interchanged with other brands that use the same mounting nomenclature. Shaft measurements and flange diameters usually match between manufacturers, but always verify the critical dimensions before replacing. If the part does not have a legible code, we identify it by its dimensions and quote it for you.

Frequently asked questions
- What does the numeric suffix in GRHA codes mean?
- The number after GRHA indicates the shaft diameter in inches or millimeters, and the hyphenated suffix specifies the exact measurement. For example, GRHA204-12 corresponds to a 3/4" shaft. To choose, measure the shaft diameter and check the series table.
- Can a GRHA unit be replaced by one from another brand?
- Yes, as long as the mounting dimensions match: shaft diameter, distance between holes and height. Equivalent series from other brands are usually interchangeable, but verify the critical dimensions before installing.
- How is a GRHA hanger bearing unit lubricated?
- The insert has a grease channel accessible from the housing. Apply lithium or compatible grease according to the duty cycle, generally every 500 to 1000 hours. In dirty or humid environments, shorten the interval and check the sealing.
