SNL split plummer block bearing housings have much more to offer...

SKF are able to offer the perfectproduct partnership - synonymouswith operational reliability, qualityand versatility.

SNL bearing housings enable thefull service life potential of theincorporated bearings to be exploitedwith less need of maintenance.

Standard SNL housings are available for shafts from 20 to160mm diameter; together with the

new SNL 30 and SNL 31 range forshafts from 150 to 500mm diameter.

Standard features● Easy installation● Reinforced design● High load carrying capacity● Relubrication facility as standard● Condition monitoring options● Wide range of sealing solutions

Application benefits● Long service life● Robust design● Reduced maintenance costs● Insensitive to excessive

tightening● Reduced lubricant consumption

Housing bore dimensions

● Improved bearing seating quality.

● Bearing seating diameter androundness tolerances tightened.

● Dowel hole positions increased to four.

SNL features

● Guarantees axial movement of free bearing, lower bearing temperature, longer bearing lifeand longer seal service life.

● Improves bearing running performance and reduces running temperatures.

● Greater accuracy and stabilityin mounting process.

Your benef its

Housing design

● Designed on a modular basis.

● Interchangeable with the previous SNH models.

● Housing painted black.

SNL features

● Allows a wide choice of bearingsincluding spherical roller bearings, self-aligning ball bearings or CARB.

● No changes required in set-updimensions.

● Improved rust protection throughnew paint additives, providing sound and compatible base for final finish.

Your benef its

Breaking load kN

● Cross webs added to base of housing give enhanced heat transfer characteristics betweenplummer block and support.

● Unique marking on cap and base therefore eliminating risk of mixing caps when mounting.

● Centre marks on housing base.

● Web supporting bolt loads.

SNL features

● Lower running temperature,longer relubrication intervals,lower grease consumption andlonger service life.

● Reduces premature bearing failure because of loss to bearing seating tolerance.

● Easier housing alignment therefore quicker installation.

● Avoids seating deformations and allows lighter support plate.

Your benef its

SNL’s high material strength and stiffness

Seal options

● All existing accessories such asas seals are compatible with SNL.

● Clear mounting instructionsprovided with all seal packages.

● Chamfers between shaft bore and seal grooves.

SNL features

● No changes required in set-updimensions.

● Mounting procedures improved.

● Easier mounting and improvedseal performance.

Your benef its

SNL’s wide range of seals

Condition monitoring

● Grease nipple fitted as standard.

● Mounting positions for condition monitoring.

● Closer tolerances for the sealgroove and shaft bore.

SNL features

● Relubrication convenience at noadditional cost, cleaner set-upconditions avoid contamination.

● Enables bearing condition to be easily monitored.

● Ensures good sealing and improved performance with both oil and grease lubrication.

Your benef its

SNL’s lubrication alternatives

Life comparison The SNL bearing housing, an integral

part of SKF’s Trouble-Free Operation
