How to distinguish between the insulation bearing cage

How to distinguish between the insulation bearing cage - 2021 02 - 24 see that some customers don't know how to distinguish between the insulation bearing cage, now, let me explain to you let everybody can better understand the insulation bearing. Steel cage: 1, cage type: two kinds of stamping and entities. 2, material: steel plate or steel forgings. 3, advantages of performance: this maintains a high strength, material is lighter. Used for deep groove ball bearing, spherical roller bearing and most of the tapered roller bearing, generally from the rolling bearing mineral oil-based or soda oil-based lubricant. 4, use restrictions: vulnerable to water, the influence of water vapor and rust. 5, working temperature: keep running temperature can reach 300 & deg; C。 Brass cage: 1, cage type: stamping and the solid two kinds, stamping only suitable for small and medium-sized. 2, material: brass, brass castings or brass forging. 3, brass with high tensile strength, mechanical strength and stamping steel cage, but relatively small density, high limit speed. 4, advantages of performance: not influenced by the lubricant, including synthetic oil and fat. 5, use restrictions: brass cage can not be used in 300 & deg; C above, is not suitable for ammonia ( Such as cooling) , because of ammonia will cause brass seasonal broken. 6, work temperature: temperature is below 300 & deg; C。 Polyamide ( Nylon 66) Cage: 1, cage type: entity cage, Injection molding in) 。 2, material: polyamide ( Nylon 66) 。 3, advantages of performance: the polyamide nylon material elasticity and the advantages of light weight, this kind of cage has a very good sliding and self-lubricating properties, especially suitable for the vibration impact stress or add and subtract speed or high bearing inner and outer circles appear when inclined to each other. 4, use restrictions: polyamide nylon cage may be affected by special lubrication ( The corrosive additive in lubricant) Cannot be applied to vacuum, because it will become fragile due to dehydration. 5, work temperature: temperature is below 120 & deg; C is greater than - 40 & deg; C temperature is too low will make nylon lose flexibility. （ Source: let cloud of hunan science and technology)
