Frequently Asked Questions
Q: What are the dimensions and specifications of the CR 6306 Z bearing?
A: The CR 6306 Z is a deep groove ball bearing with a 30 mm bore, 72 mm outer diameter, and 19 mm width. It features a pressed steel cage, shielded design, and is manufactured from high carbon chromium bearing steel conforming to SAE specifications. Precision tolerance construction makes it suitable for Crown manual pallet jack applications.
Q: Which pallet jack models use the CR 6306 Z bearing?
A: The CR 6306 Z fits select Crown manual pallet jack assemblies requiring 6306Z wheel bearings. It is interchangeable with industry standard 6306Z equivalents from manufacturers including SKF, NTN, NSK, KOYO, and FAG (6306ZR variant). Verify bearing bore and width dimensions match your equipment before ordering.
Q: What bearing brands are equivalent to the CR 6306 Z?
A: The CR 6306 Z replaces SKF 6306-Z, NTN 6306Z, NSK 6306Z, KOYO 6306Z, and FAG 6306ZR. All maintain the same 30 mm bore, 72 mm OD, and 19 mm width dimensions. This cross-compatibility allows use of equivalent OEM bearings if the CR 6306 Z is unavailable.
Q: What is the material composition of the CR 6306 Z bearing?
A: The CR 6306 Z bearing rings and balls are manufactured from high carbon chromium bearing steel that conforms to SAE standards. The pressed steel cage provides durability in material handling equipment. This composition ensures extended service life under typical pallet jack load cycles.
Q: Why does the CR 6306 Z have a shielded design?
A: The shielded design of the CR 6306 Z protects internal bearing components from dust, moisture, and debris commonly encountered in warehouse and production environments. This helps prevent premature wear and maintains consistent performance in manual pallet jack wheel assemblies.
