The clearance of an oiless bearing has to be made slightly larger to allow for heat release and lubricant film thickness than that of general oil supplied plain bearings.

deva.eco sliding bearings are thin-walled, rolled bronze parts with lubrication deposits. They can take high loads and enable compact, economic bearing design solutions.
There are three basic designs:
deva.eco 9 with rombic shaped rolled lubrication pckets. This design is mostly used in applications where nearby design elements, such as gears, are oil-lubricated. Likewise these bearings can be used with standard pumpable greases or lubrication pastes.
deva.eco 8 has lubrication pockets like deva.eco 9 but filled with solid lubricant to allow operation without additional lubrication. If higher lubrication performance is required deva.eco 7 is better suited. This type includes punched holes aslubrication deposits and is used for applications which are frequently relubricated. Due to the shape of the lubrication deposits this type is less suitable for oil lubrication.

Sintered bronze
Our range of oil-impregnated sintered bronze bearings is intended for use in maintenance-free operations, under moderately high speeds and low loads.
Solid bronze
We also produce a range of solid bronze bushes in a variety of alloy compositions.
Thin-wall solid bronze: MBZ-B09TM, LDTM, LDDTM
Our range of mono-metal bearing products is complemented by a range of thin-wall solid bronze bushes for grease-lubricated applications.
MBZ-B09 materials are provided with a uniform pattern of indents that act as grease reservoirs.
In contrast, LD and LDD materials are provided with perforations that allow larger amounts of lubricant to be incorporated. LDD is also supplied with an integral sealing arrangement.

OILES 500SP1
High-strength brass base/ Plugged solid lubricants bearing
STANDARD PRODUCT
CUSTOMIZED PRODUCT
Metal bearing with wide range of technical achievements
OILES 500 SP1 is a self-lubricating bearing for heavy load applications. It consists of a high strength brass alloy base, prepared through an advanced casting technique in which for self-lubricating feature a proprietary solid lubricant buried therein.
Features:
- Exhibits incomparable performance under high load, low speed operation. Usable without lubrication.
- Excellent wear resistance in such places where an oil film is difficult to be formed due to reciprocating, oscillating motions and frequently intermittent operations.
- Remarkable resistance to corrosion and resistance to chemical attack.
- Available in various dimensions as standard or customized product.

Cast bronze with graphite oilless bearings
650# material is made of strong cast bronze based metal with special solid lubricants embedded. The base metal withstands high load and the solid lubricants provide for self-lubrication. The bearing shows excellent performance without pre-lubrication under conditions of extreme high/lower temperature with low speed.
This material provides a maintenance-free bearing solution, particularly for high load, intermittent of oscillating motion.
