Timken Type E housed units, available from Motion, feature premium tapered roller bearings, high-performance seals, e-coated housings and locking collars. According to Motion, the design and materials improve performance in the most severe applications, resulting in elevated uptime, lower maintenance costs and an overall lower cost of ownership. Motion says the seals feature better grease retention, less contaminant ingress and better protection against water, mud and salt ingress. The collar has maximum corrosion resistance, providing better locking strength and cutting down set screw backout. The housing resists corrosion better than black oxide or powder coatings, Motion adds, featuring interchangeable bolt holes and shaft centerline dimensions.
Plummer block series added to product offering
NTN Bearing Corp. of America.’s SNC plummer block series features two-part bearing housings in metric dimensions, presenting a heavy-duty solution that simplifies the mounting and maintenance of the units. Combined with precision-made, self-aligning Ultage spherical roller bearings, NTN says its new units offer benefits in terms of service life and running behavior. With a variety of sealing systems available, NTN says the two-part bearing-housing setup provides a versatile, modular approach to a mounted-unit design, offering technically and economically viable solutions for almost any application. Complete units come with the necessary hardware for installation and maintenance, providing users with an out-of-the-box solution that minimizes downtime.
Planetary gear units offer power, flexibility and reliability
The P2.e series of planetary gear units is available for the torque range 24.8 kNm to 124 kNm. According to SEW-Eurodrive, these two- and three-stage planetary gear units cover gear ratios of 15.2 to 332. With a compact design, flexibility and a high-thermal limit rating, SEW Eurodrive says the gear units are an ideal solution for continuous heavy-duty applications where space is tight. An optional integrated fan in the motor interface aspirates air radially, accelerates it and generates a cooling stream of air with a high-flow rate. Besides its high-power density, the company says the P2.e series has a best-in-class thermal limit rating.
Design enhances drum motor safety
The motor, gear reducer and bearings of GrizzlyDrive drum motors are enclosed and protected inside the drum and designed for 80,000 hours of continuous operation before maintenance. According to VDG (Van der Graaf), the design increases safety while decreasing maintenance and operating costs. With VDG IronGrip lagging, the company says the GrizzlyDrive delivers 40 percent more traction and improved tracking while increasing lagging and belt life. The all-enclosed design and construction of the GrizzlyDrive reduces the cost of ownership, VDG adds, and provides conveyors with reliability, longevity and performance in harsh environments.
