How the SL014934 model number is decoded
envelope 170×230×60 mm with a 30.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 435 kN and C0 930 kN; with a C/C0 ratio of 0.47 the 60 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 116 kN, the limiting speed 1,580 r/min and the thermal reference speed 1,010 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 2.56 kN per millimetre of the 170 mm bore and 7.25 kN per millimetre of the 60 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 7.35 kg (7350 g) (0.53 g per mm² of the 230×60 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads at 170 mm bore this is among the largest catalogue sizes; the 1,580 r/min limiting speed confirms a slow-speed, extreme-load application such as a slewing or rolling-mill position As the fixed (locating) bearing it takes the thermal-expansion thrust from the shaft while the paired floating bearing moves; the limiting speed here is 1,580 r/min The locating structure has an axially split outer ring with ribs on both sides, joined by retaining rings, and an inner ring with a centre rib — the 60 mm width houses two complete roller rows Typical applications include construction machinery slewing drives, material handling conveyor pulleys and planetary gear bearing positions, where the 230 mm outside diameter and 435 kN dynamic rating match the duty. In construction machinery slewing drives the unit fits a compact 170 mm seat, and in material handling conveyor pulleys the 7.35 kg mass is part of the rotor inertia calculation. Designers also specify it for planetary gear bearing positions, relying on the 60 mm width and the published 930 kN static rating. The bearings cannot accommodate angular misalignment; check shaft and housing parallelism before blaming the bearing for edge spalling. Press-fit the correct ring: the rotating ring needs interference while the floating ring must slide on its seat to perform the non-locating function.
Typical equipment & failure modes
Common applications
- rope drums and winch drums
- compact slow-speed agitator drives
- marine and offshore winch arrangements
- hydraulic pumps and radial piston pumps
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
- The bearings cannot accommodate angular misalignment; check shaft and housing parallelism before blaming the bearing for edge spalling.
- Press-fit the correct ring: the rotating ring needs interference while the floating ring must slide on its seat to perform the non-locating function.
- 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.
Frequently asked questions
What are the dimensions of the SL014934?
The SL014934 is a SL0149 double-row full-complement locating cylindrical roller bearing with 230 mm outside diameter, 170 mm bore and 60 mm width, envelope 170×230×60 mm. Mass is 7.35 kg.
What does the SL014934 designation mean in the FAG/INA HR1 catalogue?
SL014934 identifies this SL0149 double-row full-complement locating cylindrical roller bearing in the Schaeffler HR1 rolling bearings catalogue. The envelope is 170×230×60 mm and the catalogue ratings are C 435 kN, C0 930 kN, Cur 116 kN.
What is the load capacity of the SL014934?
The basic dynamic load rating C is 435 kN and the basic static load rating C0 is 930 kN; the fatigue load limit Cur is 116 kN.
What is the maximum speed of the SL014934?
The limiting speed is 1,580 r/min and the thermal reference speed is 1,010 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 SL014934?
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.
