Retaining compounds
High and medium strength retaining compounds for cylindrical joints of bearings, bushes, gears and shafts; types for repairing worn seats and high temperature types.
A bearing spinning in its housing or a bush working loose usually means replacing the part; a retaining compound takes the place of a press fit, secures the joint in place and also saves the worn seat. We select the right product for the gap, load and temperature of the joint. We ship retaining compounds from stock across Türkiye and abroad, and also sell them through hidroticaret.com, our online store (Turkish).
Types
High strength retaining compounds
Permanent retention of bearings, bushes and gears on shafts and in housings.
Medium strength retaining compounds
Cylindrical joints that need to be disassembled later.
Worn seat repair types
High viscosity; fills the large gap in worn bearing seats and bushes.
High temperature types
Retaining compounds that keep their strength at high operating temperature.
How to select
Retaining compounds are liquids that fill the gap between parts in cylindrical fits (bearing, bush, shaft and hub) and cure in the absence of air. They can replace a press fit or be used together with one to increase the load that can be transmitted; they also prevent fretting corrosion.
The gap determines the viscosity: low and medium viscosity for close fits, high viscosity for worn seats. If the joint will be disassembled later, a medium strength product is selected. The table below lists the products in stock.
The surfaces are degreased; cure slows down on passive surfaces such as stainless steel and plated parts, and a suitable product is selected for these surfaces.

Frequently asked questions
My bearing is spinning in its housing, what can I do?
If the wear is small, a high viscosity retaining compound fills the gap in the seat and secures the bearing. If the wear is large, repair of the seat is assessed separately.
Can a bearing fitted with retaining compound be removed?
With a medium strength product, by standard methods; with a high strength product heating may be required.
Can retaining compound replace a press fit?
In most joints, yes; used together with a press fit it increases the load that can be transmitted.
Can retaining compound be used on drinking water equipment?
There are types marked as approved for drinking water.
