CEROBEAR GmbH

About us

Germany based CEROBEAR is a specialist for custom engineered, hybrid- and all-ceramic rolling bearing solutions. We have a long tradition in supplying high performance bearing solutions to the gas explorating, gas processing and gas distributing industries.

CEROBEAR bearings operate seamlessly in liquefied gas pumps (LNG, LH2, LOX...), gas compressors, gas expanders, refrigerant pumps, gas turbines, orc turbines and other rotating equipment.

CEROBEAR’s unique combination of advanced bearing materials and application specific bearing design, results in an unrivaled reliability and bearing life, particularly under critical lubrication conditions, at highest speeds, extreme temperatures or in corrosive environment.

Thus, CEROBEAR bearings widen the field of operation and help to significantly increase productivity and cut operating costs.

CEROBEAR Hybrid-Ceramic Ball Bearings for LNG pumps

CEROBEAR‘s rolling bearing specification for the use in cryogenic environment features races either made from AISI 440C or High-Nitrogen Steel Cronidur® 30. High-Nitrogen Steel provides excellent resistance against wear, fatigue and corrosion, particularly in combination with rolling elements made from silicon nitride ceramic (Si3N4), a material which provides inertness, extreme hardness (1550 HV) and almost perfect corrosion resistance.

Si3N4 rolling bodies, available as balls or rollers, prevent adhesive wear and significantly reduce abrasive wear and bearing friction. Therefore, CEROBEAR hybrid ceramic bearings are especially qualified for media lubrication operation. Their application specific internal bearing design considers the different thermal expansion of the races and balls and by this leads to an optimized internal geometry at operating temperature. The result is an extended bearing life.

CEROBEAR Hybrid-Ceramic Bearings

Hybrid-Ceramic Bearings using Si3N4 rolling bodies in combination with advanced bearing steels provide up to 100 times longer life

Conventional steel bearings are overburdened for many applications. CEROBEAR Hybrid-Bearings offer an interesting and economical alternative where bearings are exposed to:
High Hertzian Stress (highly loaded bearings)
Highest speed (nxdm ≤ 3.8 million mm/min)
Extreme temperatures (-253 °C ≤ application temperature ≤ 800 °C)
Corrosive environment (moisture, salt, liquefied gases etc.)
Deficient lubricant conditions (minimum amounts of lubricant or media lubrication)
