Dichtomatik N70331 O-Ring, 331 Dash Number, 2.225 in ID x 2.645 in OD, Nitrile Rubber, 70 Shore A Durometer, Import
O-rings are closed circular rings of circular cross-section. They are made through vulcanization from form tools as a complete ring. The sealing function of the O-ring is achieved by the deformation of the cross-section when installed and compressed in its housing. The O-ring can be compressed either radially or axially in its installation housing. In operating conditions the pressure exerted by the media reinforces the sealing function, as under pressure the elastomer material functions as a non-compressible fluid.

- Good chemical resistance to mineral oils and greases
- The physical and chemical resistance properties of NBR materials are determined by the acrylonitrile (ACN) content of the base polymer which can vary between 18 and 50%
- Low ACN content ensures good flexibility at low temperatures, but offers limited resistance to oils and fuels
- As the ACN content increases, the low temperature flexibility reduces and the resistance to oils and fuels improves
- Physical and chemical resistance properties of NBR materials are also affected by the cure system of the polymer
- Peroxide cured materials have improved physical properties, chemical resistance and thermal properties as compared to sulfur-donor-cured materials
- Standard grades of NBR are typically resistant to mineral oil-based lubricants and greases, many grades of hydraulic fluids, aliphatic hydrocarbons, silicone oils and greases and water to about 80 deg C
- NBR is generally not resistant to aromatic and chlorinated hydrocarbons, fuels with a high aromatic content, polar solvents, glycol based brake fluids and non-flammable hydraulic fluids (HFD)
- NBR also has low resistance to ozone, weathering and aging, but in many applications this has no negative effect

Gates® Power Transmission PowerGrip® Twin Power® TP390L050 Light Timing Belt, 1/2 in W, 39 in OAL, 3/8 in Pitch, 104 Teeth, Neoprene
PowerGripâ„¢ Twin Powerâ„¢ Timing Belts are suitable for all industrial serpentine applications that require rotation reversal in some driven shafts. Twin Power belts have precision-formed elastomeric teeth on both sides to provide high-loading capacity synchronization from both driving surfaces. Due to its double and directly opposite teeth, Twin Power synchronous belts ensure high loading capacity on contra-rotating drives and ensure smooth running and high flexibility. Gates PowerGrip Twin Power belts are designed to perform at high speeds and in extreme temperatures, with a larger tooth profile for increased performance capacity.
Browning® mounted ball bearings feature multiple housing styles, materials and configurations, an extended inner race insert bearing with ball riding nylon retainer. The insert features a rivet to prevent outer ring rotation and is available with setscrew, eccentric, or BOA concentric locking collar. The contact seal, with black oxide treated flinger provides a good balance between contaminant resistance, grease loss and friction. Depending on your preference, these bearings are available in inch and metric bore with a wide variety of cast iron, stamped steel or rubber mount housings or specific industry solutions as illustrated on the pages to follow.
