Bearings of the pillow block type are protected by a cover which extends over the pillow block and is shaped to substantially follow the contour of the pillow block and includes a slit (36) from a lower edge of the device to an opening (34) for allowing the shaft to pass into the cover to the opening (34). The cover is formed from polypropylene which is highly flexible and resistant to impact damage. Grease can be inserted into a recess or clearance between the end face of the bearing and the inside surface of the cover. In an alternative arrangement, the cover can be formed in tow parts to be clamped on respective sides of plates supporting the bearing. Again there is provided a slit and a central opening to be inserted over the shaft. |
