BC1-0738 A Cylindrical Roller Bearing 40x80x18mm TS16949 QS9000

1. Product Overview

BC1-0738A is a special single row cylindrical roller bearing exclusively designed for Atlas series air compressors, widely recognized as non-standard compressor dedicated roller bearing. Standard metric boundary dimensions: inner bore d=40mm, outer diameter D=80.2mm, overall width B=18mm.

Adopts optimized E-type roller and steel cage integrated structure, uniform roller load distribution, effectively resist instantaneous impact load generated by high-speed operation of air compressor rotors. Ultra-precision mirror grinding rolling surface minimizes friction loss, reduces operating temperature rise and abnormal noise during long-time continuous operation. All rings and cylindrical rollers are made of fully quenched high carbon chromium GCr15 bearing steel, with high hardness, strong wear resistance and stable dimensional precision. It is the core rotating spare part of screw air compressor rotor assemblies, also applicable to high-speed rotary industrial equipment with compact installation space.

3. Core Advantages

1. Compressor exclusive customized size, perfectly matched Atlas screw air compressor rotor shaft, no modification required during replacement, direct aftermarket interchange.
2. E-type optimized cylindrical roller structure, large contact area, strong bearing capacity, stable operation under continuous high-speed rotation of compressor.
3. Low friction mirror superfinished rolling raceway, effectively control heat generation, avoid bearing overheating failure under long-time full-load compressor operation.
4. C3 enlarged internal clearance design, reserved expansion space for high-temperature rotor operation, prevent roller jamming caused by thermal expansion.
5. Integral stamped steel retainer, firm roller limit, no roller deviation or shedding under high-speed alternating impact load.
6. Full quenching heat treatment process, surface hardness up to HRC60-65, outstanding anti-fatigue and wear performance, extend compressor maintenance cycle.
7. Compact thin-width integrated design, save internal assembly space of air compressor host, adapt to miniaturized compressor unit layout.
8. Comprehensive customized service: P4/P5 high precision upgrade, OEM laser marking on outer ring, neutral export carton anti-rust packaging, special high temperature grease pre-filling.

8. FAQ

1. Q1: What equipment is BC1-0738A mainly used for?
   A1: It is a special bearing for Atlas screw air compressors, installed on the front and rear support positions of the compressor main rotor, also suitable for other high-speed rotary blowers and vacuum pumps.
2. Q2: Why adopt C3 clearance for BC1-0738A?
   A2: The air compressor rotor will generate obvious thermal expansion under long-time high-speed operation, C3 enlarged clearance can effectively avoid bearing seizure caused by thermal expansion extrusion.
3. Q3: Can BC1-0738A directly replace the original imported compressor bearing?
   A3: Yes, overall boundary dimensions, load parameters and clearance grade are completely consistent with the original standard, no shaft or housing modification needed during replacement.
