Cylindrical Roller Bearings For Heavy Duty and Energy Applications
Bearings for positions where cages fail first: low speed high load, shock loading and heavy radial duty.
In frac pump power ends, conveyor chains and mill drives the cage is usually what fails. Full complement construction removes that failure path and raises load rating in the same envelope.
Bearings We Supply
Full complement cylindrical roller bearings from 20 mm to 1200 mm, plus N28 conveyor chain rollers and track roller bearings.
Full Complement Cylindrical Roller Bearings for Frac Pumps
Cageless full complement bearings for frac pump power ends running at 100-150 MPa discharge pressure.

Why Plants Source Bearings From Ascon
What defines this range.
Roller Count Above 95 Percent
Full complement construction reaches roller count typically above 95 percent of theoretical maximum, against 60-70 percent for a caged bearing.
Documented Materials
Ultra clean high carbon chromium bearing steel with controlled carburizing or induction hardening, and full traceability where the programme requires it.
Separable Construction
SL series bearings are separable, which makes mounting practical where both rings need an interference fit.
Application Scenarios
Applications.
Hydraulic Fracturing Pumps
Power end and connecting rod positions running at 100-150 MPa and 200-400 rpm.
Wind Turbine Yaw And Pitch
SL18 series bearings with advanced sealing and quality certification.
Conveyor Chains
N28 roller wheels with dynamic ratings from 133 kN to 306 kN.
Technical Reading
How Frac Pump Bearing Quality Keeps A Fracturing Job On The Design Curve
Displacement, pressure and uptime are one chain in hydraulic fracturing, and the power end bearing sits in the middle of it.

Belt tracking, energy consumption and wear patterns all trace back to the roller wheel, not the belt.

Why full complement instead of caged?
Roller count rises from about 60-70 percent to above 95 percent of theoretical maximum, and there is no cage to deform under pressure pulsation or shock loading.
Can you match our bearing designation?
Yes. Send the designation stamped on the bearing, or the housing and shaft dimensions with the clearance class.
Do you supply documentation?
Yes, including full traceability and quality certification for wind energy and other qualified programmes.
What sizes can you cover?
SL series from 20 mm to 1200 mm, N28 conveyor rollers from 19.2 mm to 41.75 mm bore, and track roller bearings such as NUKR 35.
What matters most for bearing life in frac service?
Oil cleanliness. NAS 7 is the minimum we specify, and contamination control affects life more than any other maintenance factor.
What do you need to quote?
Bearing designation or boundary dimensions, application and duty data, clearance requirement, documentation needs and annual quantity.
