We manufacture copper-based bearings and guide elements with solid lubricant deposits called "MFA“.
Mode of operation:
The Oilless bushes/bearing supplied by Avi Sales Corporation are maintenance free and are ideally suitable to oscillatory motion, linear motion, difficult working environment, high temperature application, etc. These can also be replaced with sintered bronze bearings to obtained much higher working life and better load carrying capacities. The Oilless bearings/ bushes give much higher life when compared with conventional bearing.
These Graphite Embedded Bearings have @20-25% Graphite inserts on the walls/surface that provide lubrication at all times also brings down the co-efficient of friction.
Oilless Bearings/ Bushes are self-lubricating Bearings prepared for heavy load application under Low/High speed operating conditions. According to the application in industrial field, wide ranges of Oilless Bearings/ Bushes are being manufactured by Avi Sales Corporation in all sizes as per the customers’ requirements.
|Inner Diameter||from 8 mm to 50 mm|
|Outer Diameter||As per RFQ|
|Length||10 mm to 150 mm|

Oilless Guide Bushing are a type of graphite plugged bronze bushing. As it’s used together with guide pin for mould tool making. People called it as oilless guide bushes or Oilless Guide Elements.
Oilless Guide Bushing with embedded solid lubricants are used in applications of linear or rotary motion in tool making, general machine construction and similar engineering application. The structure of the base material provides closely spaced deposits of solid lubricant. The oilless guide elements satisfy highest demands in terms of load bearing capacity at low sliding speeds, within an extensive temperature band.
The lubricant deposits are arranged in staggered geometrical patterns, thus ensuring optimal lubrication effect along the sliding motion, especially with counter bearings which are hardened and ground. The sliding surfaces should be lightly greased with lithium grease emulsion, prior to commissioning. On flat guide ways and pillar guides, from 25 to 30 per cent of the sliding surfaces consist of lubricant deposits. Surfaces of counter bearings must have a ground finish, preferably with a lay parallel with the sliding motion.
Advantages of Oilless Guide Bushes and Guide Elements
Widely used in the Casting Machines, Steel Rollers in Metallography, Mineral Machines, Ships, Turbo generators, Hydraulic Turbines and Injection Molding Machines for Plastics, etc.
