Moisture and Contaminant Exposure

Solution: Bearings in the pulp, paper, and wood industry are frequently exposed to high levels of moisture and contaminants, leading to premature wear and failure. Our specialized bearings with advanced sealing technologies provide superior protection against moisture and contaminants, ensuring longer operational life and reduced maintenance costs.

Intense Heat and High Speeds

Solution: High temperatures and fast-moving machinery can cause traditional bearings to overheat and fail. Our high-performance bearings are engineered to withstand intense heat and high speeds, featuring materials and lubricants that maintain integrity under extreme conditions. This ensures consistent performance and minimizes downtime.

Heavy Loads and Mechanical Stress

Solution: The heavy loads and mechanical stress inherent in the pulp, paper, and wood industry demand robust bearing solutions. Our bearings are designed with enhanced load-bearing capabilities and superior fatigue resistance, providing reliable operation under the most demanding conditions. This translates to improved efficiency and longer service life for your equipment.

System monitoring and preventive maintenance measures

Capital-intensive paper lines require constant availability, which is provided by top quality equipment and intelligent lifecycle service that leaves nothing to chance. This in turn calls for reliable products and services for mounting, lubrication, alignment, and condition monitoring for the rolling bearings used worldwide in the “pulp and paper” industry

Tailor-made monitoring systems for the paper industry detect damages at a very early stage. This increases planning security: Unplanned downtimes are avoided, and bearing replacement can be arranged in advance. Primagra Oman experts support paper production around the world with state-of-the-art technology, such as through remote diagnosis via the Internet or GSM.

Extremely High Demands:

Rolling bearings in paper machines face significant challenges such as moisture, intense heat, shaft deflections, high speeds, and long lifetimes. Reliable bearings are crucial for high paper quality. Primagra Oman continuously develops and maintains products to provide reliable and cost-effective solutions.

Special products for harsh environment

TL Series Spherical Roller Bearings

TL SRBs provide superior resistance to inner ring fractures, ideal for papermaking machinery operating under high-temperature conditions.

This tough, long-life series helps boost productivity and lower costs.

Features

NSK proprietary steel and special nitrocarburizing treatment dramatically improve resistance to inner ring cracks
Increased raceway surface hardness extends life
Dimensional stability under high-temperature conditions (Max. 200°C)

High Performance Standard Bearings for Industrial Machinery: Spherical Roller Bearings

Provide a longer service life and higher limiting speeds by employing cutting-edge materials and technology combined with years of cultivated experience and technical know-how.

Features

2x bearing life (25% higher dynamic load ratings)
20% higher limiting speeds
Dimensional stability under high-temperature conditions (Max. 200°C)

Molded-Oil™ Bearings

Molded-Oil bearings are lubricated by an oil-rich solid resin material in the bearing.

Oil slowly seeps from the resin over time to provide ample lubrication over extended periods.

Features

Long life
Specially designed to keep contaminants out and prevent water or other liquids from washing out the lubricating oil.
Low torque
Molded-oil material is applied after a special surface treatment to keep torque low.
Clean
No risk to surroundings from grease leakage or stray oil.
Supports high speeds
Optimized materials and molding processes allow high-speed operation.

Triple Ring Bearings

Uniquely structured, highly precise, and creep-resistant, triple ring bearings offer long life while being easy to handle and mount.

Features

High load capacity design
Vacuum-melted, carburized steel for long life
High precision
An optimized inner ring design improves lubrication
Holes and grooves on the rings make lubrication easy
