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
