Nitro Engine Bearings - MX Precision High Speed Si3N4 Hybrid Ceramics & Steel
Steel and Ceramic Engine bearings to suit a large range of Nitro Engines. MX Series Ceramic Bearings are a new design of engine bearing with Offset Internal Track for greater load capabilities, a stronger, thicker PA46 Retainer for greater resistance to high nitro content fuel, rated at over 60,000 RPM. Grade 5 Ceramic Balls for closer tolerance.
Simply select the sizes to suit your engine and select either Ceramic Hybrid or Steel.
Bearing Materials
Silicon Nitride Ceramic Balls (Si3N4)
• Very good corrosion resistance to water, salt and chemicals
• Good high temperature performance up to 1,000°C
• Non magnetic and electrically insulated
• Lighter than steel balls
• Very low heat expansion, less expansion and contraction between heating and cooling.
Ceramic Bearings can run faster than all steel bearings due to the lower centrifugal force generated by the ceramic balls, the speed increase for Ceramic Bearings is 30 - 40% with adequate lubrication. Ceramic Bearings are less subjected to ball skidding under initial acceleration / torque. This allows the bearing to last longer and be far more reliable. Low heat expansion allows the bearing retainers to last longer. There are no downsides to Ceramic Bearings other than they cost more to manufacture.
PTFE Heat Resistant Rubber Seals
• Excellent corrosion resistance to water, salt water and most chemicals
• Good high temperature performance.
• Non magnetic
• Only semi-precision grade is possible
• Maximum temperature 260°C
The PTFE Seal is rubber bonded to a metal washer. The inner lip of the seal rubs against the bearing inner ring to provide an effective seal against smaller particles such as dust and moisture while preventing lubricant leakage.
Bearing Retainer / Cage
Retainers keep the balls evenly spaced around the raceway preventing ball to ball contact and thus allowing higher speeds. They also help to retain grease around the balls and raceways. For greater accuracy and to prevent any additional friction, it is important that the retainer is not allowed too much radial movement.
Our Ceramic bearings use a Polymite Retainer.
Why Buy Plaig Bearings
Plaig Bearings have been put to the test since 2008, with over 500,000 Bearings being sold across Australia. Our bearings have been tested under the harshest conditions, by the best RC Drivers, Fishermen, Engineers, Cyclists and Hobbyists.
There are many theories on what makes a good bearing, but putting it to the test in the harshest conditions possible is the only way to practically assess whether a bearing will stay in one piece or not. The best RC drivers with the best cars will not sacrifice a trip interstate or even internationally, to have a bearing failure during a critical race.
The best Fishermen do not want a Reel failure whilst reeling in that big fish. Many professionals put their trust in our Bearings. Value for money is a priority for Plaig Bearings, providing exceptional quality for reasonable prices is what we do best.
