Bolt ball bearing units, under normal circumstances, have a large bearing capacity and can be applied to various support structures with limited installation sizes. Before the bearing is installed, an appropriate amount of grease is generally injected. Therefore, under normal circumstances, after the product installation is complete, the user does not need to enter the lubricating oil alone. The product’s cover is closed, which has the advantage of being able to seal but can slip in a small axial environment.

GJP 1 1/4″ Bearing Housing UCP207-20 with solid base type housing. Which has grease fitting on 45 degree angle, and the insert bearing has a wide inner ring with two set screws for locking on the shaft, bearing insert and housing are normally assemblied with J7 tight fitting, this items are widely used.
The ball bearing units use round metal balls to operate, which belong to point contact, so it is easy to activate the operation. In addition, the ball bearing units are used in conjunction with the spring, so the metal ring outside the ball bearing is supported on the top of the spring, so that the weight of the entire fan blade rotor is located on the ball bearing units, and is indirectly supported by the spring, so it can be used for portable products in different directions and angles should still be prevented from falling, so as to avoid damage to the ball bearing units, resulting in noise generation and reduction in service life.
The hardness of the cage is lower than that of balls and rings, and its materials are metal (such as: medium carbon steel, aluminum alloy) or non-metal (such as: Teflon, PTEF, polymer materials). Ball bearing units have less rotational friction resistance than journal bearings, so at the same rotational speed, the temperature due to friction will be lower.
Ball bearing units are generally used in equipment with low load mechanical transmission. Because the bearing area of the ball bearing is small, it is very prone to serious mechanical damage under the condition of high-speed operation. Therefore, needle roller bearings are often used in heavy-duty mechanical transmissions to increase the bearing surface, improve mechanical transmission efficiency, and reduce mechanical damage.
The ball bearing has changed the friction mode of the bearing, and adopts rolling friction, which more effectively reduces the friction phenomenon between the bearing surfaces, improves the service life of the fan bearing, and thus prolongs the service life of the radiator.
1. Bearings during transportation
One of the most typical uses of ball bearing units is in the field of transportation, since all modes of transportation (except walking) rely on wheels or rotating parts. A common use for ball bearings is in skateboard and bicycle wheels; likewise, they are found in unicycles and trikes, as well as any other application that utilizes a wheel for rotation. In self-driving cars, ball bearings are essential. The minimum number of bearings in a car is estimated to be 36, with most car models containing many more. They are used in gearboxes, wheels, engines, gearboxes, air conditioning compressors, suspensions, and more. Conceivably, they are also critical to aircraft manufacturing and any other type of vehicle such as motorcycles, tractors and construction vehicles.
2. Bearings for household equipment
The average household has at least 15 different appliances that use bearings, and this is a conservative estimate. Ball bearings are used in refrigerators, air conditioning units, ovens, dishwashers, generators, washers and dryers, microwave ovens, blenders, ceiling fans, vacuum cleaners, food processors, and even kitchen or bathroom drawers.
3. Bearings for personal equipment
In addition to typical household appliances, many personal devices also contain bearings. This could include DVD players, computer fans, game consoles, exercise equipment, ATMs, etc. Although you may not directly interact with the bearings very often, you will rely on them for most routine tasks. If you use any electrical equipment, it will most likely use ball bearings. Even in more basic items, such as bar stools or yo-yos, ball bearings are used to facilitate rotational motion.
4. Manufacturing and Industry
Ball bearings are required in manufacturing equipment in food processing, plastic and paper product production, and nearly every consumer product imaginable. The agricultural industry uses a wide variety of ball bearings in a variety of equipment that produces, packs and transports all the food we consume. Bearings in construction equipment are used in the construction of all the homes and buildings in which we live and work.

We have one experience that our bearings products were stopped by customs to get rid of all anti-rusty oil when send by airshipment, do you have this experience? How will GJP solve it?
Yes, in our business running year since so many times, GJP used to have three times this situation, one time, our Germany customers need us to airship 600pcs of PNA-30/52 needle roller bearings, when we declare the customs in Xiamen Gaoqi Airport, we’re requested to brush out all the anti-rusty oil on the bearings, as it is the regulation for the airline company, at that time, it’s our first experience, and we’re shocked because if we ship out the bearings without anti-rusty oil, the bearing would easily get rusty, after discussing with customers, finally we replaced for our customers from our factory with the bearings which did not contain anti-rusty oil and when cargo arrives customers’ place, customers re-put the oil on the bearings by themselves.
