LIGHT SERIES<br />
RAL-NPPB NON-RELUBRICATABLE TYPES<br />
• RAL series are high-quality, compact, low-cost bearings and are intended<br />
for use in lightly loaded applications.<br />
RAL series are on extended inner-ring type with self-locking collars.<br />
• Prelubricated RAL series incorporate the positive contact, land-riding<br />
R-seal. The seal has proved effective in the retention of lubricants<br />
and exclusion of foreign matter under extreme service conditions.<br />
• RAL-NPPD-series bearings have spherical outside diameters providing<br />
unrestricted initial alignment.<br />
• This bearing is used in housings with corresponding spherical inside surfaces.<br />
Suggested shaft tolerances:<br />
1⁄2 in. – 1 1 ⁄4 in., nominal to -0.013 mm, -0.0005 in.<br />
