As a leading manufacturer specializing in heavy-duty industrial bearings, Henan San Kuang Machinery Technology Co., Ltd. leverages over a decade of engineering expertise since 2014 to deliver robust solutions for demanding applications. Our Long Service Life Spherical Roller Bearing, specifically pre-greased for cement vibrating screens, is engineered to withstand the extreme shock loads, heavy contamination, and constant vibration inherent in cement production. This bearing is not just a component; it is a critical investment in reducing unplanned downtime and maximizing your screening equipment's operational efficiency.
This bearing is meticulously designed to excel in the harsh environment of cement vibrating screens. Its core advantages and technical specifications are detailed below:
- Extended Operational Lifespan: Manufactured from high-grade, through-hardened bearing steel, the rollers and raceways are optimized for superior fatigue resistance. The internal geometry of the spherical design allows for minor misalignments, distributing loads more evenly and preventing premature failure.
- Precision Pre-Greasing: Each bearing arrives factory-filled with a high-quality, high-temperature resistant grease formulated for vibrating machinery. This initial lubrication is crucial for immediate startup protection and ensures optimal performance from the first moment of operation, eliminating the risk of dry starts.
- Robust Construction for Harsh Conditions: The bearing is built to handle the abrasive dust, particulate matter, and moisture commonly found in cement plants. Optional sealing solutions, such as labyrinth seals with grease purge features, are available to provide an enhanced barrier against contaminants, further prolonging grease life and component integrity.
- Optimized for Vibratory Stress: The design incorporates features to mitigate the damaging effects of constant vibration. A sturdy, precision-machined cage (available in steel or polymer) securely positions the rollers, minimizing friction and wear even under dynamic, oscillating loads.
The technical specifications for common models are outlined in the table below. Custom configurations regarding dimensions, internal clearance, and sealing are available upon request to match your specific vibrating screen model.
| Parameter | Specification / Description |
|---|---|
| Bearing Series | 22300 Series, 22200 Series, 21300 Series (Common) |
| Bore Diameter (d) | Range from 40 mm to 200 mm (Customizable) |
| Outside Diameter (D) | Corresponding to standard dimension series |
| Width (B) | As per standard series dimensions |
| Dynamic Load Rating (C) | High capacity design for shock loads |
| Grease Type | High-temp, lithium complex or polyurea based |
| Sealing Options | Open, RS-type rubber seals, or labyrinth seals |
Benefits to Your Operation:
- Reduced Maintenance Costs: The long service life and effective sealing minimize the frequency of bearing replacements and re-lubrication intervals.
- Enhanced Equipment Reliability: Consistent performance reduces the risk of catastrophic screen failure, ensuring continuous production flow.
- Improved Safety: Reliable bearing operation contributes to overall equipment stability and reduces hazards associated with sudden breakdowns.
- Lower Total Cost of Ownership: While the initial investment might be comparable, the extended lifespan and reduced downtime lead to significant long-term savings.

Frequently Asked Questions (FAQ):
-
What makes this bearing suitable for cement vibrating screens?
This bearing is specifically designed with a spherical roller design to accommodate shaft misalignment and heavy shock loads common in vibrating screens. The pre-greasing and optional robust seals protect against the abrasive cement dust environment. -
How long is the "Long Service Life" typically?
Service life varies based on operating conditions (load, speed, contamination). However, through superior material selection, heat treatment, and lubrication, this bearing is engineered to significantly outlast standard bearings in similar harsh applications. -
Can I use this bearing if my screen is from a different manufacturer?
Yes, as long as the dimensional specifications (bore, OD, width) match your equipment's requirements. We offer a wide range of standard sizes and can also provide custom solutions. -
Is the pre-applied grease sufficient for the entire bearing life?
While the high-quality initial grease provides excellent startup and extended service, periodic re-lubrication is recommended for maximum lifespan, especially in severe-duty applications. The re-lubrication interval depends on specific operating conditions. -
What sealing options are best for high-dust environments?
For severe cement plant conditions, we recommend labyrinth seals or non-contact seals. They offer effective protection against dust ingress without the added friction of contact seals, which is beneficial for vibrating equipment. -
Do you provide technical support for bearing installation?
Yes, we provide detailed installation guidelines. Proper mounting, including correct fits and alignment, is crucial for achieving the promised service life. Our team can offer guidance upon request. -
What is the lead time for orders?
Lead times vary based on order quantity and specification. Standard sizes are typically available from stock or have shorter production cycles. We strive to provide accurate timelines upon receiving your inquiry. -
Are your bearings certified?
Our manufacturing facility operates under an ISO 9001 quality management system, ensuring consistent production quality and process control.
