Hardened sleeve for seal location

Background
- Shafts with seals to seal bearings are used in many mechanical sub-assemblies such as: pumps, gears and gearboxes
- These sleeves are used to prevent premature wear of the shaft in contact with the seal
- Using these sleeves simplifies maintenance and reduce the manufacturing costs of the shaft
Innovation
- The vast experience of JESA for heat treatment and grinding manufacturing is utilised
- Producing the steel diameter in accordance with manufacturers’ specifications
Solution
- Use of stainless steel or chrome steel
- Heat treatment to achieve a hardness of 60 HRC or more
- Sleeve range is produced by plunge grinding
- Geometry and precision of these parts are in according with DIN 620 (standard bearings)
Customer benefits
- These JESA sleeves allow customers to implement a cost effective solution, with quality production of the parts
- Simplifying maintenance
- Each sleeve can be a specific product design that can be easily integrated into the design of the final customer product
