PROBLEM TO BE SOLVED: To provide a bearing having high possibility to be substituted for bearings of various conditions, being easily maintained, and simplifying replacement and recycling of components in comparison with a very precise and fine commonly-used bearing. SOLUTION: A packing 6 is mounted on a pin roller main body 3 provided with a roller 1 attached by a shaft 2, and the pin roller is inserted to a mounting table 4 and fixed by a cover nut 5 to be sealed. A projecting width of the roller 1 is finely adjusted by the packing 6. When an object 0 to be held is the shaft, this roller bearing takes a role of ordinary bearing, and even when the object is a screw, the bearing which is generally difficult, is available. Further this roller bearing can cope with reciprocating motion though it is difficult by commonly-used rolling bearings. Further according to this invention, a state of the bearing can be easily confirmed, and the bearing can be replaced without being wholly disassembled, though it is generally difficult to confirm a situation of the bearing.
