The LP System Option
Knowing how much and how often lubricant can be introduced to the critical contact areas of the bearing is the primary challenge to obtaining proper lubrication of any bearing. A common practice in a two-row bearing is to provide a single grease-injection inlet between the two bearing rows. Over time, this practice can cause uneven lubrication of each row due to aged grease accumulating near the grease inlet. This accumulation then forces fresh grease to follow a path of least resistance, potentially starving grease to one of the bearing rows.
Timken’s LP system addresses this issue by offering a low-pressure centralized lubrication system that directs grease inlets and uses an active purging method to reliably lubricate bearings. With this system, a central pump automatically delivers lubricant through a supply line to multiple banks of injectors. When used with tapered roller bearings, each injector bank operates independently to lubricate each bearing row at the small end of the roller.
The lubricant naturally pumps to the larger roller end where the grease is then “charged” into an outlet port and suction elements, which are powered by the grease pump, pull the old grease to a convenient waste container. This design uses a combination of bearing and tribology knowledge to create a high performing system.
Each standard LP system contains our high performance pump, solenoid switch, proximity switch, two banks of three injectors, and two suction devices. Waste containers come in various options.
Benefits:
Maximizes bearing life by ensuring precise amounts of lubrication are delivered to each bearing row
Includes a patented charger that extracts old grease to a convenient waste container
Features low bearing cavity pressure for reduced contact seal wear or use with non-contact seals
Offers optimal grease fill for lower bearing temperature and torque loss
Creates less waste by preventing over-lubricating
The HP Series Option
The economical HP system provides automatic lubricant delivery through a single divider block which displaces a fixed amount of lubricant to each lube point on the bearing assembly. A moving indicator pin attached to the divider block allows for easy monitoring through a proximity switch. Injected grease creates pressure in the system to force out old grease into disposable waste containers.
Each standard HP system contains our high performance pump, series progressive divider, proximity switch, and connector. Waste containers come in various options.
Benefits:
- Offers a cost effective lubrication option for wind turbine main-shaft bearings
- Promotes a safer work environment compared to manual lubrication
- Provides more reliable lubrication than manual methods
