SL183044-A-C3

Engineered for brutal radial loads, the SL183044-A-C3 is a full complement cylindrical roller bearing that ditches the traditional cage to pack in the maximum number of rollers. With a footprint of 220mm x 340mm x 90mm, this unit is a heavy hitter in gearbox and transmission assemblies where space is tight but torque is high. The C3 internal clearance is the "secret sauce" here-it provides that vital extra buffer for thermal expansion, ensuring the bearing doesn't seize when things get hot under continuous operation. Rated for a dynamic load of roughly 1150 kN, it's built to handle the kind of stress that would buckle standard caged alternatives.

What sets the SL183044-A-C3 apart is its semi-locating design, featuring a double-ribbed inner ring and a single-ribbed outer ring. This configuration allows for controlled axial displacement in one direction, making it an essential component for shafts that need to "float" slightly during thermal cycles. Despite its hefty 27.8 kg build, the precision is top-tier, meeting standard tolerance classes for seamless integration into existing INA-style setups. You're trading off a bit of top-end speed (limiting at ~1140 rpm) for massive gains in rigidity and life expectancy. If your priority is reducing unscheduled downtime in mill or mining equipment, this full-complement roller set is the logical choice.
