PRELUBRICATED

Turner bearing units come standard with an approximate 1/3rd grease fill. The bearings contain Shell Gadus S2 V220 (Lithium 12 Hydroxy-based grease). Because the bearings come from the factory prelubricated, you should not typically need to add grease to the unit before placing it into service.

RELUBRICATION

Depending on the application, relubrication may be necessary to maximize bearing life. In these instances it is important to add only the amount of grease listed in Table 1. The purpose of this relubrication is to ensure that your bearing is not running dry, but take care not to overfill your bearing. Ideally, a 1/3rd grease fill should be maintained.

See Table 2 for information on the frequency of relubrication intervals. Please note that relubricating a bearing may cause the operating temperature of the bearing to increase. This increase is temporary and the bearing should return to normal operating temperature after a short period of time.

BEFORE RELUBRICATION

• Ensure that the grease you intend to install is compatible with previously installed lubricant.
• Clean the grease fitting and surrounding area.
• Clean nozzle or tip of greasing equipment.
• For best results, the bearing should be in rotation during relubrication.
• Filling a stationary bearing then quickly firing up equipment will often lead to bearing seal damage.

OVER-LUBRICATION WARNING

In most environments, completely filling a bearing with grease may significantly decrease bearing life. Do not relubricate a bearing with more lubricant than listed in Table 1. Unless your bearing is in a very dirty or wet environment, avoid the practice of pumping grease until you feel resistance, or until lubrication is emitted from bearing seals.
