Rotary Bushing

Swivel type lead-bronze bushed trunnion bearings are generally furnished on large diameter ball Mills. The bearing swivels are of Meehanite metal spherically turned outside and bored and faced inside to receive the removable bushing. The bushing is bored and scraped to fit the mill trunnion. The bushing is provided with end flanges thus assuring that the trunnion flanges run against a bronze face.
On smaller mills rigid or swivel type bearings support the mill trunnions. The lower half of such bearings are lined with bronze or a special mill babbitt which is peened in place and bored to fit the trunnion.
In all cases a low bearing pressure is maintained to assure freedom from overheating, long life and minimum maintenance. They are designed to provide support to the mill proper, its media and pulp load.
Trunnion bearings are generally supplied with seals for use with a circulating oil lubrication system. They can be designed to accommodate block grease or oil with wool waste.
For special applications trunnion bushings can be furnished constructed of Micarta to allow water lubrication or oil lubrication.
In many dry grinding applications, or where heat is developed, the trunnion bearings can be furnished for water cooling. This system carries away the excess heat transmitted through bearings and protects them.

Babbitt is a mixture of lead and tin, and for obvious reasons much softer than your crankshaft. It is normally 80-1/4 percent lead, 14-3/4 percent antimony and 5 percent tin. This material will serve as a durable bearing for wear surfaces for years if oiled well and not run hot. Our main products are babbitt bearings,bearing bushings,plain bearings, metal bearings, bearing housing, ring gears, crusher spare parts and other related parts which covered construction machinery, heavy machinery, electric power, metallurgy, mining and other machinery manufacturing industries. We are not only equipped for Chinese domestic market, but also exported to Europe, Asia, Africa and the America. Our factory has independent alloy casting technology and processing technology as well as a reliable quality assurance system.

Steam turbine bearing is one of the key components of steam turbine. Under the lubrication and cooling of circulating lubricating oil, it supports the heavy-duty and high-speed turbine rotor.
ZSnSb11Cu6 tin-based alloy, compared with all Babbitt alloys, ZSnSb11Cu6 has the smallest coefficient of linear expansion, thermal conductivity is 30% ~ 60% larger than lead-based alloy, which has the highest corrosion stability and anti-fatigue strength, suitable for the operation on a shaft with a particularly high load and moderate hardness of about HB300. Therefore, babbitt bearings are widely used in steam turbines as bearing pads for rotor-supported bearings.
Our factory process, repair and retread all types of steam turbine bearings according to customer's drawings. The OEM and ODM customization services are provided.
