Grease Fittings
To maximize bearing life, be sure you relubricate units with a NLGI #2-compatible grease at intervals recommended for your application. Apply lubricant through the unit’s grease fitting. Fitting threads are based on shaft size:
| Shaft Size | Grease Fitting Thread |
|---|---|
| Up to 1-7/16 in | 1/4 - 28 UNF |
| 1-1/2 in & over | 1/8 - 27 NPT |
TRITAN offers three types of fittings. A type (straight) is standard on relubricatable pillow blocks, flanges and take up units. B type (45°) and C type (90°) can be purchased separately or ordered with the units.
