るものである。 Embodiments of the present invention will be described below with reference to the accompanying drawings.Generally, as shown in FIG.
is attached, and furthermore, seal plates 3, 3' are attached to the outside thereof. Reference numeral 4 represents a lubricant supply hole provided in the radial direction of the bearing body 1, and reference numeral 5 represents a lubricant supply hole in the axial direction orthogonal to this. A lubricant is injected into the lubricant supply hole 4 through a supply port 6 provided on a lateral side surface of the bearing body 1 . The lubricant is generally grease, and is injected from the grease nipple 7, but is not limited thereto. code 8
is a through hole provided in the center of the return cap 2 at a position corresponding to the lubricant supply hole 5, and a pair of grooves 9 and 10 are formed from the outer end of the through hole 8 as shown in FIG. through holes 11 and 1 are formed on the outer surface of the supply grooves 9 and 10, respectively.
2 is provided. From the inner ends of the through holes 11 and 12, as shown in FIG. Previously grooves 14 and 16 were provided, respectively. Therefore, the lubricant injected through the oil supply port 6 passes through the supply holes 4 and 5 provided perpendicularly in the bearing body, passes through the through hole 8 provided in the return cap 2, and collides with the seal plate 3. and change course laterally. The balls then pass through grooves 9 and 10 provided in the return cap 2, respectively, through through holes 11 and 12, and are further divided into two directions from grooves 13 and 15 to the upper ball deflection groove 1.
7, 19 further passes through grooves 14, 16 to reach lower ball deflection grooves 18, 20. In this way, lubricant is supplied to the four raceway surfaces as the balls circulate.

れる。 In the above embodiment, the upper ball deflection groove 17,
When lubricating the tank 19, the lubricant must flow from the bottom to the top, so there is a possibility that the lubricant will not be sufficiently supplied. Therefore, as shown in FIGS. 4 and 5, through holes 21 and 22 are provided at the midpoint between the grooves 9 and 10, and are located above the upper ball deflection grooves 17 and 19. Groove 2 leading from the inner end of 22 to the upper ball deflection grooves 17 and 19
3 and 24 to supply oil to the upper ball deflection groove, more complete supply of lubricant can be achieved. It goes without saying that various modifications other than the above can be considered. Furthermore, if the axial supply hole 5 in FIG. 1 is provided in the opposite direction and the ball return cap 2' is also provided with similar through holes and grooves, the lubricant can be supplied more effectively.

いる。 Since the present invention is constructed as described above, four raceway surfaces can be refueled at the same time with one refueling port.
It has the advantage of providing good lubrication, and since both sides of the ball return cap are effectively used, it has the effect of enabling a compact design.
