Drawn Cup Needle Roller Bearing, Outer Ring
NTN
A bearing in which an outer ring is formed from a thin steel plate by precision drawing, the raceway surface is surface-hardened, and then a needle-shaped roller and a retainer are assembled.[Features]・ It has the smallest cross-sectional height of any bearing with an outer ring, enabling space reduction and cost savings.・ Compact design is possible with the shaft directly as the raceway surface without using the inner ring.・ The outer ring has a structure in which the needle roller and the retainer are not separated.・ Retaining rings are not required for fixing in the axial direction by simply press-fitting into a rigid housing with an appropriate fit.[Applications]・ Heavy load, high speed, gearbox for automobiles, etc.・ Steel equipment, mining / construction machinery, machine tools.

FAQ Roller Bearings
- Question: What are the different types of roller bearings?
- Answer: The different types of roller bearings are:
1. Cylindrical Roller Bearings: Suitable for moderate-speed operations with high radial-load capacity and moderate thrust loads.
2. Spherical Roller Bearings: Designed to carry heavy axial and radial loads at high speeds, even with misalignment or shaft deflection. Available with cylindrical or tapered bores.
3. Needle Roller Bearings: Feature thin, long rollers for high radial load capacities in limited space and high-speed rotational applications.
4. Tapered Roller Bearings: Support radial and thrust loads, commonly used in automotive wheel hubs, gearboxes, and industrial equipment. Available in inch and metric sizes. These bearings find applications in various industries, including heavy equipment, machinery and manufacturing. - Question: What are the advantages of using roller bearings?
- Answer: Here are some Advantages of roller bearings:
1. Reduced friction for lower starting and running friction, except at very high speeds.
2. Ability to withstand momentary shock loads.
3. Accurate shaft alignment.
4. Low manufacturing cost.
5. Moderate lubricant requirements and low friction.
6. Capability to support both radial and axial loads.
7. Long bearing life.
8. Suitable for mass production with stable quality.
9. Can support combined radial and thrust loads simultaneously. - Question: How do I choose the right roller bearing for my application?
- Answer: Here are some steps to guide you in selecting the appropriate bearing:
1. Load Requirements: Understand the magnitude and direction of the load to determine the appropriate load capacity.
2. Speed: Consider the rotational speed of the application to ensure it aligns with the bearing's capabilities.
3. Environmental Conditions: Evaluate temperature, humidity, and exposure to contaminants to select a bearing that can withstand the operating environment.
4. Bearing Type: Choose from various types like cylindrical, spherical, needle, or tapered roller bearings based on load, speed, and operating conditions.
5. Bearing Material: Select suitable materials such as stainless steel, chrome steel, ceramic, or plastic, considering load, speed, temperature, and environmental factors.
6. Lubrication Needs: Determine lubrication requirements, including type, viscosity, and replenishment intervals, to ensure smooth operation and longevity.
7. Special Features or Requirements: Consider any specific features like seals, shields, precision tolerances, or coatings needed for your application. - Question: Can roller bearings handle axial loads?
- Answer: Yes, Roller bearings can indeed handle axial loads, though most are designed primarily for radial loads. Certain designs, such as cylindrical roller bearings with flanges on both inner and outer rings, and axial spherical roller bearings, are capable of supporting axial loads. However, roller bearings generally have lower axial load capacities compared to radial loads.
- Question: How do I maintain and lubricate roller bearings?
- Answer: The guidelines for maintaining and lubricating roller bearings effectively including
1. Selection of Lubricant: Choose lubricant based on application and environment, such as mineral oil, synthetic oil, or greases like lithium soap or polyalphaolefin.
2. Lubrication Techniques: Utilize methods such as oil drip feed or grease lubrication.
3. Lubrication Schedule: Establish a schedule based on application and environmental factors and regularly inspect bearings for wear and adjust the schedule accordingly.
4. Monitoring Performance: Regularly monitor for signs of issues such as increased vibration, excessive heat, lubricant loss, or contamination and address any problems promptly to prevent premature bearing failure. - Question: What are the signs of roller bearing failure?
- Answer: Signs of roller bearing failure include excessive vibration, increased temperature, noise, lubricant contamination, and friction. Initial indicators often begin with abnormal vibration, progressing to elevated temperature and noise. Contaminated lubricants exacerbate friction, leading to heat generation and eventual failure.
- Question: How long do roller bearings typically last?
- Answer: The lifespan of roller bearings is determined by factors like rotations or operating hours, with fatigue symptoms indicating failure. The L10 life, representing the hours or rotations before 90% of bearings fail, estimates bearing life. Ratings are based on hours at a set speed, influenced by load, speed, lubrication, and conditions. Average roller bearing life is usually 4 to 5 times the L10 life, potentially longer under favorable conditions.
- Question: Can roller bearings be used in extreme temperatures?
- Answer: Roller bearings have differing temperature thresholds depending on their design, lubrication, and operational conditions. Traditional bearings can typically function in temperatures up to 149°C, while specialized high-temperature bearings can endure temperatures up to 450°C. However, excessive heat can decrease efficiency, induce wear and expansion, and compromise seals or grease. It's vital to select appropriate bearings and lubricants tailored to specific applications and environmental conditions to ensure optimal performance and longevity.
