Cuscinetto radiale a sfere SNR 6206F604, Diametro esterno: 62 mm | Larghezza: 16 mm | Diametro interno: 30 mm

Cuscinetti a sfere a contatto radiale TOPLINE, gabbia in acciaio stampato, schermi su entrambi i lati, applicazioni fino a 350°C.

This product of the SNR brand is a reliable solution for applications with very high temperatures and low rotational speeds. It was designed to combine protection, durability and performance and is ideally suited for mechanical systems exposed to severe thermal stresses. Thanks to its special design, the bearing ensures long-lasting performance even under extreme conditions while providing smooth, low‑friction running.

Features:
This Topline-Serie deep groove ball bearing is single‑row and equipped with a robust yet lightweight steel sheet cage. It is filled at the factory with a high‑temperature lubricant specifically designed for extreme thermal environments. The internal radial clearance is significantly increased (C5) to accommodate substantial thermal expansion. This configuration is ideal for low to moderate speeds up to a maximum of 50 U/min and withstands temperatures up to 350 °C. A special surface treatment, consisting of phosphating and a MoS₂ coating, improves dry‑running lubrication and provides enhanced oxidation protection. The bearing has good radial load capacity and tolerates limited axial loads in both directions.

Maintenance:
The bearing is designed to be maintenance‑free, provided it is mounted correctly and operated within the defined service limits. It is supplied from the factory with a special grease based on polyalkylene glycol and solid additives that offers high thermal stability and long‑lasting lubrication. No re‑greasing is required over the product’s entire service life. Because there is no contact between the deflectors and the rolling elements, wear is reduced and internal cleanliness is maintained.

Sealing:
This model is fitted on both sides with non‑contact metal cover discs. These steel sheet covers form an effective barrier against solid contaminants such as dust or metal particles. A V‑shaped groove in the inner ring face creates a labyrinth sealing effect that prevents ingress of dirt while retaining the lubricant inside. This sealing system protects the bearing without hindering rotation and makes it ideal for low‑friction applications. Note, however, that protection is limited in humid or corrosive environments.

Brand information:
SNR is a brand of the NTN‑Gruppe, a world‑leading supplier in the field of drive technology. With a presence in numerous countries, SNR offers innovative solutions for the automotive, industrial and aerospace sectors. The brand’s mission: reliable, high‑performance and easy‑to‑integrate products. For over 100 years SNR has supported professionals with recognized expertise and consistently high manufacturing quality.

Strengths:
• High temperature resistance up to 350 °C thanks to the high‑temperature lubricant and enhanced surface treatment
• Minimal maintenance effort due to long‑lasting lubrication and efficient deflectors
• Stable mechanical properties under moderate radial loading and consistent running behavior
• Effective protection against solid contaminants through a labyrinth seal with non‑contact deflectors
• Suitable for low speeds up to 50 U/min while offering high thermal and dynamic efficiency
• Quiet operation due to reduced vibrations and balanced components

Applications:
This single‑row ball bearing is ideally suited for industrial applications with high temperatures. It is used, among others, in oven conveyor systems, production lines for ceramics or glass, paint and heat‑treatment plants, and in plastic processing equipment near heat sources. It is a perfect fit for static or slowly rotating mechanisms subjected to repeated thermal cycles.
