2. NTE Electronics 77-4010D24 High Speed Fan, Ball Bearing, Thermal Plastic Wire Lead, 40 mm L x 40 mm H x 10 mm T, 24 VDC, 7000 rpm, 7.73 CFM
Feature
High SpeedBall Bearings
26 AWG Red (+) and Black (-) Leads
11.8" (300mm) Lead Length
Description
Cooling fans are required to protect critical electronic components by keeping them at an optimal operating temperature, thus protecting against thermal variances that could harm the components and preventing a premature failure, while ensuring optimal performance. These fans utilize a propeller to create a large airflow in the direction of the axis, moving the air in a direction parallel to the axis of the blade. AC fans provide a constant flow, whereas DC fans can run at variable speeds. DC fans consume less power, generate lower levels of EM and RF interference, and are much quieter in operation, making them ideal for personal computer and server applications.3. 40mm DC Fan - UTUO DUAL Ball Bearing 12V DC Small Size Brushless Fan 40mm by 40mm by 28mm (1.57x1.57x1.1 inch)

8. 6203-2NSE Nachi Bearing 17x40x12 Sealed C3 Japan Ball Bearings
Feature
Single-row deep groove geometry for high speeds and supporting both radial and axial loadsChrome steel for durability and resistance to deformity under heavy loads
C3 radial internal clearance for radial slack between the inner and outer rings is greater than CN (normal) to compensate for thermal expansion
Rubber seals on both sides of the bearing keep the lubricant in and contaminants out
Static load rating of 4,800 newtons and dynamic load rating of 9,550 newtons
Description
This Nachi 6203-2NSE ball bearing is made of chrome steel, is double sealed, and has C3 internal clearance. It has a 17 mm inside diameter, a 40 mm outside diameter, and a 12 mm depth. This single-row ball bearing has deep groove geometry for applications that require high speeds and support both radial and axial loads. This bearing is made of chrome steel for durability and resistance to deformity under heavy loads. It has C3 radial internal clearance for radial slack between the inner and outer rings is greater than CN (normal) to compensate for thermal expansion. Rubber seals on both sides of the bearing keep the lubricant in and contaminants out. The static load rating is 4,800 newtons and the dynamic load rating is 9,550 newtons. A steel cage spaces the balls for even load distribution and prevents contact to reduce friction, vibration, and noise. The maximum speed with grease lubrication is 12,000 revolutions per minute (rpm). This deep groove ball bearing is suitable for use in applications such as transmissions, motors, and pumps.
Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. All rolling bearings are open, shielded, or sealed. Sealed bearings are lubricated with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use. The shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.

10. NTN Bearing 6203LLBC3/EM Single Row Deep Groove Radial Ball Bearing, Electric Motor Quality, Non-Contact, C3 Clearance, Steel Cage, 17 mm Bore ID, 40 mm OD, 12 mm Width, Double Sealed
Feature
Deep groove geometry for high speedsSingle row for supporting radial loads
Steel cage evenly spaces balls for reduced friction, vibration and noise
Non-contact rubber seal on both sides to keep lubricant in and contaminants out
C3 radial clearance allows thermal expansion for continuous operating temperatures up to 120 degrees C/248 degrees F
Description
Single row radial ball bearings are the most widely used bearings and utilize an uninterrupted raceway, which makes these bearings suitable for radial loads, or a combination of thrust and radial loads. This design permits precision tolerances even at high speed operation. Shielded bearings are protected on one, or both sides (suffixes Z and ZZ, respectively) by metal shields fastened to the outer ring. This close clearance labyrinth seal retains the lubricant and prevents the entrance of foreign matter. Sealed bearings incorporate steel reinforced rubber seals securely fastened to a groove on the outer ring. Contact with the inner ring is by sealing lip (Contact Suffix LLU). Or, non-contact with the inner ring is by labyrinth seal (Non-contact Suffix LLB) to provide positive sealing at all times.
NTN is one of the three largest bearing companies in the world with more than ninety years of manufacturing expertise in ball bearings.
