self-aligning ball bearing
Self-aligning ball bearings has two rows of balls and a common sphere raceway in the outer ring. The bearings are consequently self-aligning and insensitive to shaft deflections and angular misalignment of the shaft relative to the housing. Additionally, self-aligning ball bearings generate less friction than any other type of rolling bearing, which enables them to run cooler even at high speeds. Self-aligning ball bearings are available with either a cylindrical or tapered bore. Bearings with a tapered bore can be mounted directly on a shaft or on an adapter or withdrawal sleeve.
self-aligning ball bearings are available in several designs, including:
Open, basic design, bearings
Sealed, with contact seals on both sides
Open bearings with an extended inner ring
self-aligning solution for textile spinning machine
Spindles for spinning yarn require high accuracy, high speed, reliable self-aligning properties and low maintenance. self-aligning ball bearings are the appropriate solution for this application. They generate very low friction and can run at high speeds. They have the required self-aligning capabilities and are highly reliable.
Sealed self-aligning ball bearings
For trouble-free operation, offers sealed self-aligning ball bearings in the 22 and 23 series.
self-aligning ball bearings are also available in a sealed version with contact seals at both sides - designation suffix 2RS1. These sheet steel reinforced seals are made of oil and wear-resistant acrylonitrile-butadiene rubber (NBR). The permissible operating temperature range for these seals is –40 to +100 °C and up to +120 °C for brief periods. The seal lip contacts a smooth chamfer on the inner ring with light pressure.
Sealed bearings are lubricated as standard with a grease with a lithium thickener, that has good rust inhibiting properties sealed self-
aligning ball bearings are available with a cylindrical bore. Some sizes are also available with a tapered bore (taper 1:12).
Sealed self-aligning ball bearings are lubricated for the life of the bearing.
Sealed bearings are lubricated for life and require no maintenance. They should not be heated above 80 °C before mounting and should
not be washed.
An alternative to spherical roller bearings for spreader rolls
Traditionally, spherical roller bearings have been used in supercalendar spreader rolls as they were the only self-aligning bearings available in the sizes required. The range includes large self-aligning ball bearings with identical boundary dimensions to the spherical roller bearings.self-aligning ball bearings will reduce friction considerably, helping mills to:
Extend relubrication intervals and reduce maintenance
Improve supercalender availability
Eliminate paper quality problems caused by bearing heat generatio
self-aligning ball bearing has widely application:
1)self-aligning ball bearing can bear relatively large radical load and some axial load.The raceway of the external ring is spherical surface.
2)This bearing is suitable to bear large load and impact load.
3)This bearing is used in such industries as precision instrument,low-noise electric motor, automobile,motorcy,metallurgy,rolling mill,mine,petroleum,papermaking,cement and common machinery.
