(Summary description) The successful use of Timken bearing grease depends on the physical and chemical properties of the lubricant, application and environmental conditions. It is usually difficult to determine the appropriate grease for specific bearings under certain operating conditions, so you can ask the lubricant supplier or equipment manufacturer for specific requirements on equipment lubrication. General lubrication knowledge for any application can also be consulted with Timken's representative. When selecting lubricating grease, it is important to consider its consistency at working temperature. The grease shall also show no signs of gradual thickening or separation of lubricating oil, formation of acid or hardening. The grease shall be smooth, non fibrous and free of any chemically active ingredients. The drop point shall be much higher than the working temperature. This selection guide is for reference only and cannot replace the technical requirements provided by the equipment manufacturer. Grease Selection Guide: through the research on the knowledge of tribology and bearing anti friction and how the above two points affect the performance of the whole system, Timken has developed specific greases for various applications. Timken ® Grease helps bearings and related components operate effectively in harsh industrial environments.

What is clearance and how to measure the clearance of rolling bearing?
1、 Original clearance
Clearance in free state before bearing installation. The original clearance is determined by the processing and assembly of the manufacturer.
2、 Installation clearance
Also known as fit clearance, it is the clearance when the bearing, shaft and bearing seat are installed but not working. Due to interference installation, either the inner ring is increased, or the outer ring is reduced, or both, the installation clearance is smaller than the original clearance.
3、 Working clearance
When the bearing is working, the inner ring has the maximum temperature rise and the maximum thermal expansion, which reduces the bearing clearance; At the same time, due to the load, the contact between the rolling element and the raceway produces elastic deformation, which increases the bearing clearance. Whether the bearing working clearance is larger or smaller than the installation clearance depends on the combined action of these two factors.
Some rolling bearings can not adjust the clearance, let alone disassemble. These bearings have six models, namely 0000 to 5000; Some rolling bearings can adjust the clearance, but can not be disassembled. There are 6000 type (angular contact bearing) and 1000, 2000 and 3000 type rolling bearings with conical holes in the inner ring. After adjustment, the installation clearance of these types of rolling bearings will be smaller than the original clearance; In addition, some bearings can be disassembled and the clearance can be adjusted. There are three types: 7000 (tapered roller bearing), 8000 (thrust ball bearing) and 9000 (thrust roller bearing). These three types of bearings do not have original clearance; For 6000 and 7000 type rolling bearings, the radial clearance is reduced, and the axial clearance is also reduced, and vice versa. For 8000 and 9000 type rolling bearings, only the axial clearance has practical significance.

Working condition and suffix meaning of fag self-aligning roller bearing for vibrating machinery
2021-09-10
The rolling bearing installed in the vibration exciter unit of these equipment must be able to withstand heavy load, high speed, acceleration and centrifugal force. Most of these applications work in very harsh environments, such as pollution and humidity. Fag's special self-aligning roller bearing is developed for vibration mechanical conditions and has achieved great success in practical application. In particular, the cage of rolling bearing must be able to withstand the force generated by high radial acceleration. Under worse working conditions, it may also bear the force generated by axial acceleration.
The rotation of the eccentric block will cause the deflection of the rotating shaft and the relative sliding inside the bearing. This will increase friction, resulting in an increase in bearing operating temperature. The dynamic centering capacity of special self-aligning roller bearing can reach 0.15 °. If you need to provide greater centering capability, please contact the industrial application engineer of Schaeffler Group. Basic design of FAG Special self-aligning roller bearing FAG Special self-aligning roller bearing series for vibration machinery is 223, and its main dimensions comply with e DIN 616: 1995-01 and ISO 15 standards. For the special stresses generated in vibrating machinery, FAG provides special self-aligning roller bearings with suffix t41a or t41d, which are described in section 1.5.
X-life self-aligning roller bearing 223-e1 series has very high bearing capacity by maximizing the use of bearing cross-section. For vibrating machinery, the inner diameter of X-life series self-aligning roller bearings available at present can reach 220 mm. 1.2. 1 X-life 223..- E1-t41a (d) series self-aligning roller bearing fag self-aligning roller bearing designed by E1 has no flange and has very high bearing capacity. FAG Special Bearing 223 with suffix t41a or t41d designed for vibrating machinery- E1 series also has this advantage, as shown in Figure 1. This is a new fag standard design for bearings with bearing diameters from 40 mm to 150 mm (bore series 08 to 30).
