How the SL014938 model number is decoded
envelope 190×260×69 mm with a 35.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 580 kN and C0 1270 kN; with a C/C0 ratio of 0.46 the 69 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 155 kN, the limiting speed 1,410 r/min and the thermal reference speed 860 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 3.05 kN per millimetre of the 190 mm bore and 8.41 kN per millimetre of the 69 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 11.2 kg (11200 g) (0.62 g per mm² of the 260×69 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads 190 mm bore, 260 mm outside diameter: at this size the 1270 kN C0 rating and rigid full-complement pack replace multi-bearing arrangements in compact heavy-duty designs SL0149 is the double-row full-complement locating bearing: it supports the radial load and axial loads in both directions, fixing the shaft axially at that position Inside the 190×260×69 mm envelope the two cageless rows provide C0 1270 kN, the capacity this series is selected for in heavy gearbox and drum positions Typical applications include marine and offshore winch arrangements, rope drums and winch drums and hydraulic pumps and radial piston pumps, where the 260 mm outside diameter and 580 kN dynamic rating match the duty. In marine and offshore winch arrangements the unit fits a compact 190 mm seat, and in rope drums and winch drums the 11.2 kg mass is part of the rotor inertia calculation. Designers also specify it for hydraulic pumps and radial piston pumps, relying on the 69 mm width and the published 1270 kN static rating. Relubrication paths matter: specify the annular groove/hole executions where access is poor, because the tightly packed rows trap old grease. There is no cage: do not apply caged-bearing speed rules — the printed limiting speed is a hard kinematic ceiling set by roller-to-roller contact.
Typical equipment & failure modes
Common applications
- rolling-mill and steel-industry drives
- vibrating and oscillating machinery
- material handling conveyor pulleys
- construction machinery slewing drives
Known failure patterns
- raceway pitting from overloaded slow-speed positions where the cageless rollers repeatedly stress one contact band
- rib and roller-end scoring when applied axial thrust exceeds the semi-locating capacity
- roller smearing from roller-to-roller sliding at speeds above the limiting value
- edge loading and premature spalling caused by undetected shaft/housing misalignment (full-complement rows cannot self-align)
- brinelling of the raceways from static shock during mounting or transport of the heavy rotor
- lubricant starvation in the tightly packed roller set, especially in the double-row executions
- freting and creep on a loose ring seat under a rotating load
- contamination wear in open gearbox positions with damaged seals or breathers
- false brinelling from micro-movement while the shaft is stationary under vibration
Selection pitfalls — read before you substitute
- Relubrication paths matter: specify the annular groove/hole executions where access is poor, because the tightly packed rows trap old grease.
- There is no cage: do not apply caged-bearing speed rules — the printed limiting speed is a hard kinematic ceiling set by roller-to-roller contact.
- Use the rib structure correctly: SL18/SL1850 give one-direction axial guidance, SL0149 locates both ways and SL0249 floats — pairing two locating bearings on one shaft binds thermal growth.
Frequently asked questions
What are the dimensions of the SL014938?
The SL014938 is a SL0149 double-row full-complement locating cylindrical roller bearing with 260 mm outside diameter, 190 mm bore and 69 mm width, envelope 190×260×69 mm. Mass is 11.2 kg.
What does the SL014938 designation mean in the FAG/INA HR1 catalogue?
SL014938 identifies this SL0149 double-row full-complement locating cylindrical roller bearing in the Schaeffler HR1 rolling bearings catalogue. The envelope is 190×260×69 mm and the catalogue ratings are C 580 kN, C0 1270 kN, Cur 155 kN.
What is the load capacity of the SL014938?
The basic dynamic load rating C is 580 kN and the basic static load rating C0 is 1270 kN; the fatigue load limit Cur is 155 kN.
What is the maximum speed of the SL014938?
The limiting speed is 1,410 r/min and the thermal reference speed is 860 r/min. In the Schaeffler catalogue the reference speed is the thermally permissible running speed under defined load; the lower of the two values governs each application.
What is the locating function of the SL014938?
The SL0149 is a locating bearing: it fixes the shaft axially in both directions; pair it with a non-locating SL0249 at the other end to avoid binding.
