High Temp Bearings’s Dry Carbon Solid Lube (DCSL) can be used with virtually any style bearing (except needle bearings and some thrust bearings) that has a metal cage separating the balls or rollers. Bearing size can be as small an I.D. as 1/8” or as large an O.D. as 25”. To be processed with DCSL, the bearing must have a metal cage.  Some full complement bearings and wheels can also be processed with DCSL.

Bearings processed with DCSL are filled from the inner to the outer race and for the width of the bearing. The microscopic clearance between the Solid Lubricant and the metal rings of the bearing ensures protection from dirt,dust, or other contaminants.

Ontaminants small enough to migrate into the gap can not latch onto the dry solid lubricant to clog the ball path. Normally, additional seals or shield are not required, even in high contaminant areas.

The dry solid lubricant deposits a 2 micron thick film of graphite on all friction surfaces of the bearing. Because of this, and the expansion of the metal which will occur at high temperatures, the recommended clearance for applications up to 250F is C3 and the clearance for applications up to 660F is C4.

Other factors affecting bearing life, especially at high temperatures are speed and load. Ordinary steel bearings suffer significant loss of hardness at temperatures above 300F. For application above 250F, heat stabilized steel bearings are recommended. When using bearings processed with Dry Carbon Solid Lube, especially in high temperature and/or high speed applications, a slip or light interference fit is recommended between shaft and bearing.

Dry Carbon Solid Lubricants are not recommended for high impact applications.  Vibration or moderate impact will normally not effect the lubricant.

Dry Carbon Solid Lubricants are not rust inhibitors. Normal care should always be taken to protect bearings in corrosive applications.

Starting torque of bearings processed with Dry Carbon Solid Lube is similar to that of free-spinning bearings. Minimum load to prevent ball skid is similar to a dry bearing.

• Dry Carbon Solid Lubricants have a wide usable temperature range – from minus 250F (minus 160C) to plus 660F (plus 350C).
• Dry Carbon Solid Lubricants exhibit low starting torque that is constant across the entire usable temperature range.
• Dry Carbon Solid Lubricants will not be washed out by steam and are unaffected by most common solvents, acids, and alkalis.
• Dry Carbon Solid Lubricants are environmentally safe and will not drip or fling even in extreme temperatures.

• Dry Carbon Solid Lubricants will effectively seal the bearing, protecting it from dust, dirt, or other contaminants that could cause premature bearing failure.
• Dry Carbon Solid Lubricants are dry - eliminating the possibility of contaminants "sticking" to the bearing as a source of bearing failure.
• Dry Carbon Solid Lubricants have extremely low out gassing characteristics in high vacuum applications - even at very high temperatures.
• Bearings processed with Dry Carbon Solid Lubricants need no additional lubrication – ever! Reduce down time and you reduce maintenance costs!

Dry Carbon Solid Lubricants may extend bearing life ten times or more!
