Direct Lube Equalising Thrust Bearings
L – Series thrust bearings are designed and manufactured to allow equipment manufacturers and operators a high quality bearing assembly that is interchangeable with other bearing manufacturer’s designs.
L - Series are an equalising type design with six thrust pads, each with direct lubrication fed into a groove on the leading edge of the thrust pads.
They can be supplied as a single or double thrust assembly with or without the thrust collar. Machining or complete installation and supply of thermal sensors or load cells can be provided.
Below are our standard stocked sizes but assemblies can be made from 50mm (2”) up to 300mm (12”) Shaft Diameters.

Lubrication
L Series bearings use direct lubrication with oil fed into a groove on the leading edge of each thrust pad. This provides cool oil onto the leading surfaces of each thrust pad and therefore reduces peak temperatures in the bearing, allowing for better performance at higher load and/or speeds.
Performance Analysis
We can provide a full oil film performance analysis for your application based on parameters such as speed, load and lubricant type to verify safe operation of the bearing.
