SAVI‑KER Corner Bearing Application Solution

Self‑lubricating, zero‑maintenance engineering‑plastic corner bearings are specially designed for sharp belt deflection of belt conveyors. They enable smooth conveying under minimum bending radii and support efficient operation of your production lines.

The product is monolithic injection‑moulded from high‑performance engineering plastic. Balls or needle roller bearings are not required. With modified polymer composite technology incorporating high‑strength fibres and special solid lubricants, it achieves 100 % lubrication‑free and zero‑maintenance operation.

The ultra‑small outer roller diameter allows extremely compact belt deflection and minimises the gap between two conveyor belts. It effectively prevents small and delicate products from slipping or tipping at transfer points, making it an ideal choice for conveyor lines in food, packaging, pharmaceutical and logistics industries.

The customer is a well‑known domestic beverage‑packaging equipment manufacturer aiming to raise the packaging speed of its system to over 20 packs per minute. The original solution adopted metal rollers fitted with needle roller bearings, which incurred high costs and frequent maintenance. The equipment operates under harsh conditions: abrasive sugar granules, sand, dust and moisture. Conveyor belts inside the shrink tunnel are continuously exposed to high temperature of 100 °C with belt speed up to 0.9 m/s. A minimum service life of one‑year round‑the‑clock operation is required.

Integrating advanced material science and precision manufacturing processes, the SAVI‑KER corner bearing delivers comprehensive performance improvements for your conveying systems.

Lubrication‑free & Zero‑maintenance: Solid lubricants are embedded into the polymer matrix. No external grease is needed. It avoids product contamination and greatly cuts maintenance costs and downtime.

Ultra‑narrow Bending Radius: Roller outer diameter can be as small as 9 mm for highly compact belt deflection. The gap between two belts is minimised to guarantee smooth transfer of small‑sized products.

Low Drive Power: Low friction coefficient reduces power consumption, lowers operating costs and aligns with the industrial trend of energy‑saving green manufacturing.

Long Service Life: Low‑friction surface mitigates mutual wear of both conveyor belt and roller, substantially extending service life for belts and rollers.

Wear‑resistant, Dirt‑proof & Corrosion‑resistant: Insensitive to abrasive particles such as dust and sand; resistant to various chemical media for demanding working environments.

Low‑noise Operation: No metallic rolling elements generate less operating noise, delivering a better working environment and meeting noise‑reduction requirements for modern factories.

Hygienic Design: One‑piece construction without balls or needle rollers eliminates risk of grease leakage. Easy‑to‑clean design complies with hygiene standards for food and pharmaceutical industries.

Easy Installation & Replacement: Lightweight construction enables quick fitting and swapping, reducing man‑hours for maintenance and improving equipment uptime.

Working Principle & Functions

Conveyor‑belt Transfer Transition: When two conveyor belts meet, conventional rollers feature large radii and create substantial gaps between belts, where small or delicate products may fall into gaps or tip over. Thanks to its ultra‑small outer diameter, SAVI‑KER corner bearing greatly reduces deflection radius and nearly eliminates gaps to realise smooth product transfer.

Belt Return Deflection: At conveyor ends and corner positions, the knife‑edge roller guides belt return precisely, maintaining belt tension and centring to stabilise conveyor‑line operation.

Timing‑belt Precision Guidance: Suitable for accurate deflection guidance of timing belts to ensure transmission accuracy and synchronisation for high‑precision conveying requirements.

High‑speed Conveying Adaptation: High‑speed grade material withstands belt speeds up to 1 m/s, suited for high‑efficiency production scenarios such as high‑speed food conveyor lines.
