LINEAR BEARING GRADE

LINEAR BEARING GRADE

LINEAR BEARING GRADE represents a family of self-lubricating materials and is offered in standard sizes

Advantages

  • Excellent physical and mechanical properties
  • Self-lubricating with superior bearing performance
  • Good dimensional stability at operating conditions
  • Superior resistance to moisture absorption
  • High wear resistance
  • Low coefficient of friction
  • Outstanding chemical and corrosion resistance
  • Light weight and reduces noise chatter
  • LINEAR BEARING GRADE is oven annealed to reduce internal stresses

Method of Operation

LINEAR BEARING GRADE materials are used in dynamic load applications such as: bearings, thrust washers, bushings, gears, cams, spacers as well as in numerous other sliding or rotating components.

  • Bushings: radially loaded shafts, whether Carbon or Stainless Steel, can benefit from the use of LINEAR BEARING GRADE sleeve bushings
  • Thrust Bearings: under oscillating motion, these bearing materials exhibit excellent wear resistance, durability and no stick-slip. Axial- loaded shafts benefit from the reduced friction of the material
  • Linear Motion: for the benefits of efficient mechanical advantage, LINEAR BEARING GRADE leadscrew nuts provide low friction, reduced noise and combinations of high speeds/low loads or moderate speeds and loads
  • Pulleys: these bearing materials resist wear, self-lubricating, easily fabricated and can be incorporated into existing designs

Special Features

LINEAR BEARING GRADE was developed for general-purpose bearing applications. This grade exhibits an excellent surface finish when machined. Outstanding service life and superior chemical resistance are typical of LINEAR BEARING GRADE products. This grade excels in performance demands up to moderate loads and speeds.

LINEAR BEARING GRADE bearing grade material was developed to handle moderate loads in high-speed applications. Long service life, exceptionally low coefficient of friction with reduced noise plus high PV capabilities are some of the characteristic of LINEAR BEARING GRADE

Member Testimonials

ONGC – Oil and Natural Gas Corporation Limited

"ONGC - Oil and Natural Gas Corporation Limited" - Our complex drilling application where Shaft was eccentric and application was robust & muddy. Replacement was never easy. Mech Spares designed Oil seals resolved difficulty. This gave a complete joy to my maintenance team.

Kuwait National Petroleum Company

"Mr Mohammed Al Duaigy" of (Kuwait National Petroleum Company) : We tried several diaphragms from renown worldwide Rubber manufacturing companies. We found Mech Spares technical know how and product to be of great durability and lasted 3 times more then anticipated. They have accurate understanding of there products.

McCafferty BM Design Ltd, KENT United Kingdom

"McCafferty BM Design Ltd, KENT United Kingdom" - Most of the O rings manufacturing company suggested to use larger diameter and expensive elastomers. We learnt with Mech Spares that elastomer being weaker compare to metal and alloys and needs appropriate back up for high pressure or high vacuum applications. Further not necessary the most expensive elastomer is the best for all applications. We trust Mr Nilesh chodhari completely for all our O rings designing applications.

Bhabha Atomic Research Centre ( BARC )

"Dr. A. Singh" of BARC: The electric Insulation mat manufactured by MECH SPARES as per IS 15624 tested at ERTL and found to withstand 40 Kv and still didn't tear. We have been using since 5 years and still didn't generate any fatigue. They arranged bulk delivery in short period.

Tata Steel

"Tata Steel" - One of our old machines started making loud noise and disturbed the entire village. We were compelled to stop the machines which lead to huge production loss. With the help of Mech Spares designed bellows in two part we could retain the lubrication and eliminate the noise.
