The locking arrangement consists of two knurled-cuppoint set screws fitted in the extended inner ring. These set screws are tightened down onto the collar lockThis locking system is often used when vibration is aproblem.

4 The locking arrangement consists of aneccentric diameter formed on the extended inner ring ofthe bearing which engages an eccentric diameter in thebore of a separate collar. The collar is then locked inposition on the shaft with a knurled cup-point set sleeve lockThis locking system is recommended when a positiveconcentric lock is required or when heavy vibrationand/or shock load is present. The locking arrangementconsists of a standard taper adaptor sleeve, locknut andlock washer (H300 series). S LockThe new RHP S Lock shaft locking arrangement is foruse with Self-Lube mounted bearing units and inserts,where Simple, Secure and Safe locking is consists of a concentric collar fitted withtwo set screws, which contact the inner ring diameterwhen tightened. This action causes the collar and innerring to move in opposite radial directions to lock thewhole bearing assembly securely to the S Lock is designed as an alternative to the eccentric collar type for the series 1200 ECG and LPBR series has a rubber seating ring betweenthe insert and housing, and is suitable for lightapplications where noise and vibration are typesseal typesSingle lip seal (standard)The S type seal has a mouldednitrile lip bonded to a strong steelpressing secured in the bearingouter extremes of temperature,+180 C to -40 C, silicon sealsmade to the proven S type designare lip seal plus flinger sealThe Flinger Seal has a nitrilemoulded lip bonded to a steel former,which is pressed onto the bearinginner ring.

Protector for added bearing protectionand standard leaflet introduces the RHP Self-Lube range of mounted bearing units and wide inner ringbearings. Full technical details are available in our separate catalogue, RHP Self-Lube bearings . Self-Lube units provide simple and effective bearing arrangements capable of accommodatingmoderate initial misalignment from mounting errors. The range of inserts and housings cover a widevariety of styles, heavy or light applications and metric or inch reliability, simplicity and ease of assembly of items in the Self-Lube range has resulted in theirpopularity for applications such as process and automation equipment, extraction, agricultural andconstruction corrosion resistant range of bearings and housings, the RHP Silver-Lube is available forapplications where frequent thorough washdowns are necessary, optimum hygiene standards are required and good chemical resistance is important.
