Description

Material
Bronze sinterizado semelhante a SINT A50.
Versão
Impregnado em óleo (aprox. 25 por cento do volume de óleo).
Dureza mín. 25 HB.
Indicação
As buchas deslizantes de bronze sinterizado são impregnadas em óleo, autolubrificantes, livres de manutenção e prontas para a montagem. Através das forças de aderência, o óleo passará para o eixo giratório e, em estado imobilizado, será absorvido pelo mancal deslizante, através do efeito capilar. Não é necessário relubrificar em condições normais de operação.
Dados técnicos
Static load: max. 70 N/mm²
Dynamic load: max. 20 N/mm²
Friction coefficient, dry: 0.05 to 0.10
Sliding speed: max. 6 m/s
Maximum pv value: 2,45 N/mm² * m/s
Temperature range: -20 °C to +100 °C
Assembly
Press in plain bearings, do not hammer in. The use of a suitable press mandrel is advisable. Without a mandrel there is a risk that the bearing may deform during installation. After press-fitting into a housing with bore H7 the bore D has a H7 tolerance.
Tolerances
Housing:
Recommended tolerance H7.

Shaft:
Recommended tolerance h6 to h9. Hardened or non-hardened ground shafts can be used (for secondary applications drawn shafts can also be used).
