Product description

Nachi's high quality spherical roller bearings series EXQ are designed to support shafts under difficult conditions - e. g. in sheet metal rolling machines, paper mill and printing equipment, transportation equipment for mining industry, in big-sized gears for wind turbines, in drive shafts for vessels and in similiar heavy duty equipment. Compared to former designs and products of competitors Nachi's bearings have special advantages:

-Significant higher loads - up to 25 % higher radial loads
-Up to 10% higher speeds compared to already known bearings
-Optimized curvature of raceways of inner and outer rings and optimized curvature of rolling surface of rollers
-Continuous operation at temperatures up to 200 °C enabled through special heat treatment and pressed steel cages

In common Nachi's spherical roller bearings offer outstanding features to prefer them for use in heavy duty machines:

-Shaft deflection up to 2° misaligning of inner ring
-Tolerating of poor shaft alignment
-High axial load, up to 80% of the radial load
-Long lifetime due to optimized internal specifications
-Due to individual operation and environmental conditions diverse cages available
-Simple mounting
-Very robust construction
-Internal clearing can be justified through tapered-bored inner rings in conjunction with tapered shaft
-Broad range available: 25 mm to 180 mm inner diameter as a standard, up to 1000 mm inner diameter as an option
-Long lifetime due to high quality steel and special heat treatment made by Nachi
-Bearing units with diverse kinds of housings available
