Engineering specifications and dimensional capacity verified from our official company brochure.
Our Shershah workshop handles small precision printing cylinders up to large continuous textile dyeing rolls and heavy conveyor drums.
Overview of key engineering equipment used to fabricate, turn, vulcanise, and finish rollers.
Heavy bed lengths capable of turning metal cores, turning journal bearing steps, chamfering tube walls, and threading shaft ends up to brochure-stated length.
Equipped with precision stone and diamond grinding heads for cylindrical finishing, crowning, and fine micro-finishing of rubber and ebonite surfaces.
Steam and temperature controlled pressure vessels for vulcanising rubberised rollers, ensuring deep cross-linking and permanent bond with the core.
Specialised tool posts for machining spiral, diamond, herringbone, and circumferential grooves into cured rubber and metal bodies.
Inspection stands to detect and correct unbalance in hollow rolls and guide rollers, preventing severe machine vibration on high-speed lines.
In-house preparation of bonding primers and compounded synthetic formulations matching operating temperature and chemical contact.
Selected according to mechanical wear, chemical exposure, and temperature requirements.
| Material Grade | Hardness Range | Key Properties | Typical Machine Use |
|---|---|---|---|
| Natural Rubber (NR) | 30 – 90 Shore A | High tensile resilience, excellent abrasion resistance | General conveyor pulleys, nip rolls, feed rollers |
| Nitrile (NBR) | 40 – 95 Shore A | High resistance to petroleum oils, solvents, and greases | Textile finishing, printing presses, converting machinery |
| Neoprene (CR) | 45 – 90 Shore A | Excellent resistance to ozone, weather, and mild chemicals | Outdoor rollers, washing ranges, paper transport |
| EPDM / Hypalon | 45 – 85 Shore A | High resistance to polar solvents, ozone, and temperatures to 140°C | Chemical wash boxes, plastic extrusion, corona treaters |
| Silicone Rubber | 30 – 80 Shore A | Outstanding thermal stability (up to 220°C) and non-stick release | Hot foil stamping, laminators, bag making, packaging |
| Ebonite (Hard Rubber) | 98 – 100 Shore A / Shore D | Rock-hard surface, high chemical/acid resistance | Acid pickling, bleaching ranges, textile dye vats |
