Document Type and Number:
WIPO Patent Application WO/2016/204082
Kind Code:
A1
Abstract:
Provided is a lightweight and compact contact-seal type sealed bearing that can achieve tight sealing even in environments with an extremely low temperature of -100°C or lower, in environments with a high temperature of 250°C or higher, or in an environment with a large temperature change. This sealed bearing (1) is provided with an inner ring (2) and an outer ring (3) which are bearing rings, multiple rolling bodies (4) retained by a retainer (5) between the inner and outer rings, and a seal body (6) that is disposed at the opening section between the inner and outer rings and that seals the inner bearing space, wherein the seal body (6) is formed from a meta-type wholly aromatic polyamide fiber and seals the inner bearing space as a result of having one end of the seal body fixed to the outer ring and having the other end of the seal body slide along the inner ring (2) while elastically making contact therewith at a predetermined elastic deformation volume.
