Keiper belt coatings

Keiper CROMA high-performance flat belts are made of fully synthetic polyamide foils, with a one-sided or two-sided adhesion coating of chrome-split leather. Fitted with a polyamide reinforcement. With a one-sided or two-sided coating of chrome-split leather, highly resistant to abrasion and wear. Chrome-split leather is used exclusively as a friction coating on power transmission belts as an alternative to nitrile-butadiene rubber (NBR). CROMA belts with a coating of chrome-split leather are perfect for power transmission applications where the rollers are considerably contaminated by oil and dirt. In view of its slightly porous surface, chrome-split leather is air and humidity permeable and absorbs moisture; thus, it retains friction. However, the coefficient of friction of leather is lower than that for nitrile-butadiene rubber and steadily decreases during operation.

KEIPER synchronizing toothed shafts can be made of such diff erent materials as aluminum, steel or stainless steel. The fact that they can be produced with all pitches and designed according to your specifications and drawing ensures optimal solutions for all applications and any loads. Our synchronizing toothed shafts work together optimally with our extensive and complete range of timing belts. Together they are a perfectly matched system for your application. We have a large range of standard pulleys on stock, which can be reworked according to your specifi cations within a short time (e.g. bores and machining based on your drawings). Special surface coatings, e.g. such as hard coating, anodizing, zinc coating or bronzing, improve corrosion and wear resistance.
