ABSTRACT:
A linear movement guide bearing including a main body accommodating a pair of side by side roller trains is linearly movable in an axial direction along a raceway surface through rolling of the roller trains. A pair of side protection covers formed of metal plates are attached to the main body to respectively cover substantially the whole lateral sides of the main body and end caps which are fixed to axial opposite ends of the main body. A pair of end protection covers formed of metal plates are respectively fixed to outer end surfaces of the end caps to protect the end caps. The side and end protection covers insure the mechanical strength of the guide bearing against external impacts. Seal members are respectively attached to lower edges of the side and end protection covers to seal clearances between the lower edges of the protection covers and the raceway surface.
