Threaded Urethane Bumpers with Metal Core

Our threaded bumpers have a tough, solid core surrounded by a rubber exterior that withstands impact. They are often used to guard, align, and position parts on automated machinery. Plus they’re threaded so they’re easy to install and remove. Male thread bumpers and male thread hex shoulder bumpers have a rigid stud made of steel for fastening into any surface.

Medium-soft bumpers are about as hard as a pencil eraser. Hard bumpers are about as hard as a shoe heel.

Polyurethane bumpers are abrasion resistant and non-staining. For indoor and outdoor use. Temperature range is -65 degree to +200 degree F, unless noted Color is red.

Rectangular Bumpers with Metal Plate

A 1/8″ thick metal plate is bonded to the base of these bumpers for added reinforcement. They are often used to guard, align, and position parts. Bumpers have drilled unthreaded (through) holes to accommodate a mounting bolt (not included), unless noted. They’re hard like a shoe heel. Bumpers with an aluminum base plate offer the best corrosion resistance.

Polyurethane bumpers have excellent abrasion resistance and are non staining. For indoor and outdoor use. Temperature range is -65 degree to +200 degree F. Durometer=80A, Color= Red.

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.

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.
