Self Lubricating Elements

We manufacture copper-based bearings and guide elements with solid lubricant deposits called "MFA“.

Properties :

  • High Wear Resistance
  • Excellent Sliding.


Applications:

  • With high loads and low speed
  • When oil or grease lubrication are not desired or not available.

Mode of operation:

  • Deposits (boreholes or groves) of solid lubricant are distributed with a proportion from 25% to 35% in the sliding surface of the base material.
  • The overlapping geometrical distribution of the deposits assures the lubrication of the entire surface.
  • During operation, a compact adhesive lubricating layer forms on the sliding surfaces, reducing direct solid state contact to a minimum and protecting the sliding counterpart.
  • Our lubricants contain effective friction and wear reducing elements, as well as corrosion protecting supplements.
  • Metallic abrasion and impurities penetrating into the sliding area are absorbed by the deposits, avoiding greater damage to the sliding surfaces.
  • The friction in MFA bearings is influenced by operating conditions, material, roughness, as well as the hardness of the sliding counterpart. The coefficient of friction ranges from  0,04 to 0,12, reaching the upper boundary towards the end of service life.
  • The temperature range of MFA standard elements extends from -50°C to 150°C. Special designs with wider temperature ranges (up to 200°C) are available on request.
  • The friction occurring in MFA-bearings is influenced by material, roughness and hardness of the sliding counterpart, as well as from the operating data. The coefficient of friction lies in the range of 0,06 ≤f ≤0,12 with upper boundary tendency towards the end of service life.

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.

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.
