Screw Stud: Carbon steel galvanized, high strength, precise thread, securely locks to equipment or brackets without loosening.
Integrated flange and screw stud design: locates via flange face and locks quickly with stud, no extra fixtures needed, compatible with various mounting holes.
Fully enclosed cavity: blocks dust, debris, and liquids effectively, prevents ball jamming, and greatly extends service life.
Optimized ball protrusion height: uniform load distribution, 360° omnidirectional rotation for precise material steering and smooth conveying.
Operating temperature range: -30℃ ~ +80℃, adaptable to most industrial production environments.
Load capacity: 50kg – 500kg (varies by model), meeting light to heavy-duty application requirements.
The KSM SP-FL combines stainless steel construction with flange mounting for hygienic industrial environments. Designed for food, pharmaceutical and medical equipment applications. Proudly manufactured by Shandong Guanbei Bearing Technology Co., Ltd. in Linqing, Shandong — China's bearing capital. Backed by 20+ years of precision bearing manufacturing experience.
Flange-mounted stainless steel units install securely on processing equipment. Smooth surfaces prevent product buildup and allow easy cleaning. Available with food-grade grease option. Common applications include conveyor transfer tables, assembly lines, packaging equipment and specialized industrial machinery.
Each unit undergoes 10,000-cycle load testing before shipment. Standard export packaging with anti-rust protection. Samples ship within 3–5 business days. Contact us for custom specifications or bulk pricing.
