密封形転がり軸受。[Claims for Utility Model Registration] (1) With a reinforcing plate in which the elastic bulge on the outer circumference is fixed to the seal groove of the outer ring, and the elastic seal on the inner circumference forms a sealing part between it and the inner ring. In a sealed rolling bearing having a seal body, the outer ring seal groove 1
0 is the radial inner wall 11 and the surrounding wall 1 that follows it.
The reinforcing plate 42 of the seal body 4 has a concave shape with an outer wall 13 and an outer circumferential wall 4 whose outer circumferential portion on the fixed side faces inward in the axial direction from the flat portion 421.
22 and a radial outer peripheral flat part 423 following this, and the outer peripheral flat part 423 is located on the inner wall 11 of the seal groove and has an elastic bulge 4.
3, and its outer diameter D1 is formed slightly smaller than the entrance diameter D2 of the seal groove 10. (2) In paragraph 1 of the claims for utility model registration,
A sealing device for a sealed rolling bearing in which the peripheral edge of the outer circumferential flat portion 423 of a reinforcing plate has a convex strip 424 that is slightly bent axially outward. (3) Scope of claims for utility model registration, paragraph 1 or 2
2. A sealed rolling bearing in which the outer circumferential flat portion 423 of the reinforcing plate 42 is formed continuously in the circumferential direction. (4) Scope of claims for utility model registration, paragraph 1 or 2
2. The sealed rolling bearing according to item 1, wherein the outer circumferential plane portion 423 of the reinforcing plate 42 is discontinuous in the circumferential direction by notches formed at appropriate intervals in the circumferential direction. (5) Scope of claims for utility model registration, paragraphs 1 to 4
In any one of the paragraphs, the bulge 4 of the seal body
A sealed rolling bearing having a concave circumferential groove 433 on the outer surface of 3. (6) In paragraph 5 of claims for utility model registration,
A sealed rolling bearing in which the concave circumferential groove 433 is located at a position corresponding to the outer circumferential flat part 423 of the reinforcing plate. (7) Scope of claims for utility model registration, paragraphs 1 to 6
In any of the above, the outer peripheral plane portion 42 of the reinforcing plate
3, the outer diameter D1 of the seal groove 10 is smaller than the entrance diameter D2 of the seal groove 10 by about 0.4 mm to 0.8 mm.
