double row cylindrical roller bearings

Slots in the inner race spacer permit lubricant to flow from the bearing chamber to the roll neck.The inner race spacers are hardened to minimize face

All four-row tapered roller bearings are supplied as pre-set matched assemblies with all components identified to ensure correct installation sequence

Front faces of single cones and both faces of double cone are extended to contact each other.
Lubrication delivered through three cup spacers.

SL18 Series Single-row Full Complement Cylindrical Roller Bearings

SL18 Series Single-row Full Complement Cylindrical Roller Bearings

Single row bearings can be "adjusted" to the status that has required clearance(axial clearance) or pre-load for to enable it to achieve optimal perfo

This seating force prevents the rollers from skewing off apex, thereby keeping them positively aligned and located against the cone large rib.

Four-row tapered roller bearings
Their main application is on the roll necks of rolling mill equipment.

Cone spacers are hardened to reduce face wear.
Numbered serially to assure correct installation sequence.

●Vehicle front wheels
●Differential and pinion configurations
●Conveyor rolls
●Machine tool spindles
●Trailer wheels

● Widely used
● Fitted as one of an opposing pair
● Be "set" to the required clearance(endplay)
● Perload condition to optimize performance

1. This is the basic and the most widely used type of tapered roller bearing.
2. RATED LOAD: Cr= 610 KN, Cor= 1070 KN.
