The invention may further be arranged to: the joint of the main body and the sealing lip is provided with an annular notch.
Through further arrangement, a notch is formed at the joint of the main body and the sealing lip, so that the elasticity of the sealing lip can be enhanced.
The invention may further be arranged to: including the holder, the holder components of a whole that can function independently sets up and including first ring portion and second ring portion, is provided with between first ring portion and the second ring portion and constitutes a plurality of partition roof beams that both connect, partition roof beam between the interval be formed with the pocket hole that supplies the roller installation.
Through further setting, under the great condition of bearing quality, be the first ring portion and the second ring portion that can separate each other with the holder setting, can be when dismouting bearing, progressively install roller and holder.
The invention may further be arranged to: first ring portion sets up and is being close to first retaining ring department, second ring portion set up the interval department between second retaining ring and outer lane, partition roof beam and second ring portion integrated into one piece, and separate the scarf joint cooperation between roof beam and the first ring portion.
Through further setting up, second ring portion sets up the interval department between second retaining ring and outer lane, and separates roof beam and second ring portion integrated into one piece, can pack into in advance between outer lane and the inner circle with second ring portion, separate the roof beam earlier, later with the roller installation back of finishing, with first retaining ring and separate the roof beam and scarf joint, further dismouting of being convenient for mutually.
