Manufacturer: IKO
Bearing Type: Sheave Roller Bearing
Basic Dimension(s): 170mm X 260mm X 122mm / 121mm
Boundary Dimension(s):
Internal Diameter (d) = 170mm
External Diameter (D) = 260mm
Width Through Bore (B) = 122mm
Outer Ring Width (C) = 121mm
Distance Between Snap Rings (C1) = 99mm
External Diameter of Snap Ring (D2) = 270mm
Snap Ring Width (f) = 4mm
Radius (rs min) = 1.5mm (1)
Additional Dimension(s):
(S) = 11mm
(J) = 204.5mm
(c) = 3.5mm
Load Rating(s):
Basic Dynamic Load Rating (C) = 857kN
Basic Static Load Rating (C0) = 1730kN
Speed Limitation(s):
Allowable Rotational Speed = 600 r/min (2)
Note(s):
(1) Minimum allowable of chamfer dimension "r".
(2) The allowable rotational speed applies to grease lubrication. Considering that the axial load acts under practical operating conditions, upto 1/10 of this value is recommended for actual use.
Remark(s):
* The inner ring has an oil groove and two oil holes.
* This bearing is provided with pre-packed grease.
What is a Sheave Roller Bearing?
Sheave Roller Bearings are specialized bearings designed for use in sheaves or pulleys to support rotational movement under high radial loads. These bearings typically consist of a robust outer ring and cylindrical or tapered rolling elements, allowing them to handle both dynamic and static loads. They are optimized for applications where heavy-duty performance, durability, and precise alignment are critical.
Key Features:
High Load Capacity: Engineered to support significant radial loads, making them suitable for demanding applications.
Compact Design: Designed to fit within the limited space of sheaves or pulleys.
Durable Materials: Constructed with high-strength materials to resist wear, impact, and harsh environmental conditions.
Sealing Options: Available with seals or shields to protect against contamination from dust, dirt, and moisture.
Smooth Operation: Designed for low friction and efficient performance in rotating and oscillating motion.
Benefits:
Extended Lifespan: Enhanced durability reduces the need for frequent replacements.
Precision Performance: Ensures accurate and smooth operation, even under high loads.
Maintenance-Friendly: Sealed designs minimize the need for regular lubrication and maintenance.
Versatility: Compatible with a wide range of sheave and pulley designs.
Applications:
Cranes and Hoists: Supports sheaves in lifting and lowering heavy loads.
Elevators and Escalators: Ensures smooth operation of pulley systems.
Construction Machinery: Used in heavy-duty equipment such as excavators and bulldozers.
Marine Applications: Common in ship rigging and deck machinery.
Industrial Systems: Found in conveyor systems and material-handling equipment.
Sheave Roller Bearings are integral components in systems where reliability, durability, and high load capacity are essential. Their robust construction and optimized design make them a preferred choice in industries ranging from construction and manufacturing to transportation and marine operations.
