Housing – Ø Mounting bevel, min. 1.5 mm x 15-45°
Shaft Mounting bevel, 5 mm x 15°, edges rounded
Force fitting mandrel
The application of an adequate force fitting mandrel is
advisable. Maybe grease lubrication of the outer surface is
necessary when mounting.
Stick in Adhesive must not contact the sliding surface.
MAINTENANCE DGB-D1/ D2 is a maintenance-free composite
sliding bearing with solid lubricant pockets, but primary lubrication is
necessary for rigorous application as Graphite takes time to get applied on
moving parts initially. Therefore aging resistant lithium stiffened grease
should be used.

DEB RANGE: WRAPPED & ROLLED BRONZE
(CuSn8P) BACKING + POCKETS & HOLES FOR FORCE
LUBRICATION.
TECHNICAL DETAILS
(COMMON) of DEB-D1 & D2 Wrapped bronze
sliding bearing are an advancement over conventional casted & machined bushes.
High tensile and elongation properties of these bearings give it much largest
cycle life. DEB range is laminated CuSn8P (DIN 17662) construction. Produced following standard DIN 1494 / ISO 3547 Low-maintenance assured and proper
lubrication ensures much lasting service periods and reduced downtime.
DEB-D1 With lubrication pockets for retaining grease as well as
unwanted particles which may come in the sliding area protecting and
safeguarding sliding movement. DEB-D1 has
through holes which provide much more lubrication as the grease and oil medium
has much better possibility to move through covering the mating parts avoiding
friction and viz-e-viz wear and tear/ maintenance.
PROPERTIES High load capacity and stability at low abrasion, suited for rough
operation, corrosion resistant.
