HIGH-QUALITY INDUSTRIAL OIL SEALS
- Silicone. Vinyl-methyl-silicones (VMQs) maintain performance in temperatures from -140° to 392° F. In addition, silicone is resistant to adverse weather conditions, light, and ozone. The healthcare and food industry sectors, as well as pneumatic and hydraulic systems, often use silicone.
• High eccentricity-following lip shape
Type 1 - Furthermore, the use of rubber offers chemical and weather resistance advantages
Some of the uses of o-rings are pipes, plates, flanges, and cylinders. They can also be found in cameras, and scuba gear.
Full synthetic oil is ideal for vehicles that demand peak level performance and high levels of lubrication. Full synthetic oil provides higher viscosity levels, resistance to oxidation and thermal breakdown, and helps fight against oil sludge. Plus, it helps improve fuel efficiency and can even increase a vehicle’s horsepower by reducing engine drag.
Because the inner diameter of the oil seal must be stretched during assembly, it is necessary for the shaft to possess a ramped edge. The angle at which the ramped taper should be chamfered is 30° a 50°. If a flange or keyway is present on the shaft, it is best to use a bushing. The bore should also have a chamfer of 30° over at least 1 mm on the ramped side. Be sure to round off the edges properly in the process.

Put a wood block at least 6 in. (150 mm) square and 1 in. (25 mm) thick as a spacer between the jack and the sump to prevent damage.
