Accent Bearings Company, Inc. specializes in PTFE pillow bearings.
We have perfected matching the best PTFE pillow bearings with the end application. The bearing cuts down the most friction by delivering smooth metal balls or rollers along with a smooth inner and outer metal surface for the balls to roll against allowing the mechanism to spin smoothly.
There are many types of bearings; deep groove bearings, ball bearings, needle bearings, spherical & pillow bearing products, and more.
PTFE pillow bearings are also known as rolling-element bearings, are designed to carry a heavy radial load while minimizing friction by maintaining the separation between the moving parts of the bearing. PTFE pillow bearings transmit loads using cylinder rolling elements which have greater surface contact to handle larger or strenuous loads without deforming. They are better suited than balls in ball bearings for many precision applications.
PTFE pillow bearings are particularly good for applications that are hot, fast, or deprived of lubrication.
PTFE pillow bearings are used in applications such as main shafts and auxiliary drive shafts to support pure radial load, allowing for axial shaft extension because of temperature changes so there is no additional load effect on the bearing.
Rolling-element bearings are commonly used for their low rolling friction. For heavy loads and where the loads can greatly change during cornering, such as cars and trucks, tapered rolling bearings are used.
Industries that heavily rely on PTFE pillow bearings are agricultural, energy, manufacturing, marine, medical, mining, food and beverage, packaging, pulp and paper, transportation, and wastewater.
range from bearing loads of hundreds of tons to small but still demanding bearings of just a couple millimeters. PTFE pillow bearings end applications include but are not limited to aviation cargo systems or all types of conveyor belt roller systems, compressors, rocker arm pivots, pumps, turbine engines, two cycle engines, outboard engines, transmissions and gearboxes, agriculture equipment, heavy equipment, industrial machinery, solar panels, medical equipment including prosthetics, paper moving equipment, helicopter transmissions, fuel pumps, and many other uses that exceed specifications for ball bearings.
are made via steel wires die cut into cylinders making the rollers. They go through several surface finishing and heat treatment processes. Steel plates are press cut into circles, then shaped into cones, then the bottom is cut and finally it goes through a turning process.
A is cylindrical and used to provide low-friction movement for a bushing or bearing block. A ball bearing is a spherical unit that accomplishes the same objective as a PTFE pillow bearings. The real difference has to do with the contact surface between the bearing and the rail.
Accent Bearing’s specialists help ensure your bearing material selection properly satisfies the balance between the metal that is sufficiently hard and strong to prevent creep and other issues and perfectly suitable for the level of fatigue and impact resistance needed. Characteristics taken into consideration are corrosion resistance, seizure resistance, fatigue resistance, embeddability, conformability, porosity, friction coefficient, porosity, friction coefficient, thermal expansion coefficient, thermal conductivity, compressive strength, and cost.
Most bearings are made of a type of steel known as high carbon chromium steel or chrome SAE 52100 bearing steel. This is used for reasons of cost and durability. Bearings are also made from other materials such as stainless steel, ceramics, and plastic.
Bearing alloys form a special group of materials which have found wide use in the manufacture of slide bearing bushings. The bearing alloys used in commercial practice include cast irons, bronzes, and alloys based on tin, lead, zinc, and aluminum. The most common alloys are those of tin and lead.
Because applications often need high chemical inertness, self-lubricating properties, and low friction coefficients polytetrafluoroethylene (PTFE) improved with additives such as phenolics, acetal, polycarbonate (Lexan), or Nylon are the perfect hybrid solutions.
C = Dynamic Capacity (dN or Lbs) P = Equivalent Bearing Load (N or Lbs) N = Rotating speed in RPM. e = 3.0 for ball bearings, 10/3 for PTFE pillow bearings.
The bearing safety factor, or safety modulus fs, is the ratio of the basic static load rating Cor the equivalent load P on the bearing. When the use conditions are normal operation, a safety factor of 1.0 is typical.
The principal types of PTFE pillow bearings are cylindrical, spherical, and tapered.
The majority of bearing failures occur because of improper lubrication. Lubrication failure can occur if the wrong lubricant is used, if not enough lubricant is applied, or if the bearing has been exposed to excessive temperatures that have caused the lubricant to degrade. Corrosion & Contamination.
Bearings sized and measured by their inner diameter, outer diameter, and width. The size of a bearing is usually listed as such: ID x OD x W. These measurements are normally taken in millimeters but can be converted to inches.
A higher rated bearing will not make you “go faster”, but the quality of a bearing does affect your roll out. The roll out is how long your wheels will continue spinning after you push off. A better bearing will keep you rolling longer, so you can put in less effort to cover the same amount of space.
